Henry Hu

Professor Dept. of Mechanical Engineering (MAME), University of Windsor

With the rapid expansion of battery-powered electric vehicles (BEV) in the automotive industry, research interest in lightweight Al alloys and their casting processes and applications has increased considerably. The substitution of castable aluminum alloys with superior strengths and electrical conductivity for copper reduces the weight and size of electric induction motors, and improves the energy efficiency and driving range of the BEVs. The present article was intended to give a general introduction into the common cast Al aluminum alloys and their relevant processes, and to motivate the development of high strength and conductive Al alloys for practical realization of Al applications in the motors of the BEVs. A number of cast alloy systems containing Cu, Si, Ni, Mg, Fe and Ti were evaluated, in comparison to nanostructured wrought Al alloys. The conventional casting processes suitable for Al alloys, high pressure die casting, squeeze casting and sand casting, were described. Strengthening mechanisms including solid solution strengthening, precipitation strengthening, dislocation accumulation strengthening and grain boundary strengthening were presented. The phenomenon of electrical conduction for Al alloys was outlined. The mechanical properties and electrical properties of the recently developed Al alloys for casting and deformation processes were comprehensively listed and critically reviewed in association with microstructural characteristics.

Ali Nasiri

Canada Research Chair, Assistant Professor Dalhousie University

With more than 50 Mt of annual production, stainless steels have witnessed the highest production and consumption growth rate per year within the last 30 years among all other metallic materials. This demanding market needs to be supported through implementing efficient and cost-effective manufacturing techniques. In recent years, the emerging additive manufacturing technology has opened up new fabrication opportunities with customized designs, reduced production time, and improved materials consumption, fostering sustainability in manufacturing systems. Focusing on this topic, in this talk, additive manufacturing of recently developed 13-8 Mo precipitation hardening martensitic stainless steel, also known as CX stainless steel, with applications in plastic molding tools, extrusion dies, and marine will be discussed. Particular attention will be given to both small-scale and large-scale fabrication methods of the alloy employing laser powder bed fusion (L-PBF) and wire arc additive manufacturing (WAAM) processes, respectively. The pros and cons of both processes are discussed along with detailed comparisons between their as-printed microstructural features, mechanical properties, and corrosion performance.

Dr. Nasiri is an Assistant Professor and a Canada Research Chair (CRC)-Tier 2 at Dalhousie. He is also affiliated with the mechanical engineering department at the Memorial University of Newfoundland through an Adjunct Professor appointment. His research contributions lie in advancing state-of-the-art metal additive manufacturing (AM) processes toward large-scale parts production with tailored properties at drastically reduced production time and cost. Dr. Nasiri’s research is also recognized for contributions to microstructure-properties-performance relationships in additively manufactured advanced metallic materials, i.e., high strength corrosion resistant alloys and nanoparticles reinforced high strength aluminum alloys, as well as post-printing process developments for AM fabricated parts to improve mechanical integrity and service life.

Yu Zou

Professor University of Toronto

Titanium alloys and γ-TiAl intermetallics are widely used in additive manufacturing of aerospace engine components, but their complex microstructures and related micromechanical properties have not been fully explored. In this project, we employ high-speed nanoindentation mapping, electron probe microanalysis, and electron backscatter diffraction to characterize as-deposited and heat-treated Ti-6Al-2Zr-Mo-V and alloys. Our results show the correlations between mechanical contrasts (hardness and elastic modulus) and phase contrasts (α and β). The hardness and elastic modulus of the α and β phases are increased due to the element redistribution after annealing (Al diffuses from β to α; Mo and V diffuse from α to β). We also use a K-means clustering algorithm to analyze nanoindentation dataset and distinguish between α and β phases. In addition, we used the AM technique to fabricate a γ-TiAl/Ti2AlNb graded material by depositing γ-TiAl powder on a Ti2AlNb alloy substrate. High-resolution scanning electron microscope (SEM) and high-speed nanoindentation are employed to characterize the microstructure and mechanical properties of the transition zone from the Ti2AlNb substrate (disk) to the γ-TiAl alloy (blade). Our study provides a new methodology to give a better understanding of the microstructure-mechanical property relationship of additive manufactured multiphase alloys across length scales.

Hamidreza Yazdani Sarvestani

Research Officer National Research Council Canada

Traditional machining techniques pose significant drawbacks when applied to ceramics due to the material’s inherent brittleness. Specialized laser machining has been known to solve these issues through higher precision and micrometer-scale feature control. In this study, a picosecond fiber laser has been used as a material removal system for different engineering applications of industrial grade alumina ceramics with a variety of thicknesses and feature dimensions. This work explored picosecond laser process parameters such as focal position, linear speed, and wobble amplitude in order to control cut depth and optimize cut quality in terms of kerf width, kerf taper, surface cleanness, while avoiding crack formation. The surface roughness was assessed to determine the quality of the cuts. The optimal process parameters between the surface finish and material removal rate were introduced. Using a circular wobble laser pattern, it was determined that a greater cut depth can be achieved at lower linear speeds and wobble frequencies due to the higher linear energy density. It has also been found that the kerf taper is dependent on the cut depth and wobble amplitude, where the measured cuts follow the geometric relation between these parameters accurately.

Hamidreza is currently a Research Officer at National Research Council Canada (NRC). He received his Ph.D. in Mechanical Engineering from Concordia University in 2016 and he was serving as a joint postdoctoral fellow at McGill University (Bioresource Engineering Department, 2016-19), NRC (Aerospace Research Center, 2017-20) and École Polytechnique de Montreal (Department of Mechanical Engineering, 2018-19). His areas of research include design, advanced manufacturing and testing of advanced structures. His PhD thesis was the first of its kind in the world to investigate how a composite helicopter landing gear can be designed and manufactured using thermoplastic composite materials and automated fiber placement. For his joint postdoctoral research, He has been working on design, fabrication and testing of high-energy absorption architected structures including 3D-printed lightweight meta-sandwich structures (in collaboration with McGill), bioinspired architectured ceramics for ambient and high temperature applications (in collaboration with National Research Council Canada and the Department of National Defence) and multi-functional lattices with tunable Poisson’s ratio and coefficient of thermal expansion (in collaboration with Polytechnique Montreal).

Laser powder bed fusion (LPBF) is a popular additive manufacturing (AM) technique due to its ability to produce complex geometries with minimum material waste. These advantages have motivated research in LPBF processing of advanced alloy systems, including nickel-based superalloys, to create high-performing, long-lasting parts in the aerospace industry. Amongst the Ni-based superalloys, AM of Inconel® alloy 718 (IN718) has been widely studied, not only due to its outstanding high-temperature properties but also because of its good weldability. However, LPBF still has certain drawbacks that require further investigations for specific part geometries. A key concern is the poor surface quality of the LPBF fabricated parts that require post-process machining, which can obliterate the cost benefits of AM. Hence, it would be of interest to use hybrid additive and subtractive manufacturing in a single setup to produce parts with high-quality surface finishes and tight dimensional tolerances. Thus, this study investigated the application of a hybrid additive-subtractive method (Matsuura LUMEX-Avance-25) to fabricate IN718 benchmarking coupons. The coupons were then examined for surface finish both with and without high-speed machining. The microstructure of the hybrid manufactured IN718 was investigated thoroughly in the as-fabricated condition and following post-process heat treatment. Finally, hardness, tensile properties, and fracture behaviors were studied in both conditions.

Deep Decarbonization Pathways for Pyrometallurgical Processes: Opportunities & Challenges


 

Annie Levasseur

Professor, École de technologie supérieure

It is now widely recognized that human activities exert an unbearable pressure on natural resources and environment, and the metallurgy sector is no exception. Major changes at all stages of products life cycles are required in order to decrease greenhouse gas emissions that are responsible for climate change, as well as other pollutants, and to optimize the use and recirculation of resources in our current highly linear pattern of production and consumption. A wide range of solutions are possible, going from less energy intensive extraction and refining activities to the development of recycling processes. Life cycle assessment (LCA) is the preferred tool to assess potential environmental impacts of products, processes and services, while taking into account their entire life cycle. As a diagnosis tool, LCA is widely used to identify the processes that contribute the most to environmental impacts in order to prioritize efforts and make sure that the solutions proposed do not lead to higher environmental impacts elsewhere in the life cycle. In this talk, the general LCA framework will be presented, focusing on challenges and opportunities for the metallurgy sector. Case studies will also be presented to show how LCA could be used to quantify potential environmental benefits associated with different low-carbon and circular initiatives to be implemented.

Annie Levasseur is Professor within the Deparment of Construction Engineering at École de technologie supérieure in Montréal (Canada), and Chairholder of the Canada Research Chair in Measuring the Impact of Human Activities on Climate Change. She is also the Scientific Director of the Centre for Intersectoral Studies and Research on Circular Economy (CERIEC). She is a Chemical Engineer by training and has worked in the oil refining industry for 8 years prior to her academic career. She is an expert of the LCA methodology, and her research focuses mainly on climate change impacts. In addition to her research activities on environmental impacts modeling, she teaches life cycle assessment and the integration of environmental and sustainability aspects in engineering projects.

Various methods and technologies for decarbonization of ferroalloy production are available; each with their own challenges and opportunities. Their potential and the most promising method vary between the different ferroalloys as well as with location, energy mix and time frame.

Ferroalloys are industrially produced mainly in submerged arc furnaces (SAF) where electric energy is used for reduction and are supplied by electrodes to the reduction zone The main raw materials are oxides that are reduced to alloy by solid carbon. Possible pathways for decarbonization can be changes of existing processes, use of new or alternative raw materials, pre-processing of raw materials, post processing of off-gases or completely new processes, or a combination of some theese. Some examples are given in the paper.

Greenhouse gas emissions (GHC) from ferroalloy industry has decreased the last decades by changes in existing production as furnace design and improved process control. Both carbon and energy consumption has been reduced. The potential for further reduction is limited by the amount of carbon required to remove oxygen in the ore. Alternative technologies are thus sought.

Use of a non-fossil reductant as biocarbon will reduce fossile emissions and do not require any main changes in existing process. It is already in use and is often seen as the easiest solution. The main challenges are availability and to have qualities that do not reduce furnace performance or increase specific energy and carbon consumption. Pretreatment and prereduction of ores are especially relevant for Mn- and Cr- alloy production. Although this will reduce CO2 emissions, carbon is still needed for final reduction and other methods must be used in addition. Use of CO- rich off-gas as raw material for other products or carbon capture and storage of the gas, will reduce the CO2 emissions from the actual plant, but in most cases over time result in same global CO2 emissions. Recirculation of gases back to the process is a way to decrease this drawback. New, alternative methods can be gaseous reduction, mainly with hydrogen, electrolysis and metallothermi. The possibility for use of each of theese for a specific alloy depend on the reduction potential that can be obtained in the actual case. For all the ferroalloys there are technical challenges that must be overcome before such new technologies can be used. Different alternative approaches as use of plasma or new electrolytes have been proposed. A combination of different technologies is in some cases the best choice

To be sustainable and contribute to decarbonization, carbon consumption and CO2 emissions from the total value chain must be reduced. In evaluation of potentials and challenges it must thus be ensured that pre-processing, postprocessing, raw material and energy use and steps in new process does not increase total consumption of fossile carbon.

Examples of pathways for decarbonization of ferroalloy production, with focus on Mn, FeSi and Si production will be presented and discussed.

Eli Ringdalen is a senior research scientist at SINTEF working with process metallurgy mainly within Mn-alloys and Si and FeSi production. The research includes both development of new processes and optimisation of existing processes. Important research topics are properties and effects of raw materials, minimisation of energy consumption, methods to reduce CO2 emissions as well as different aspects of furnace operation.

Eli graduated from NTNU in Trondheim, Norway with MSc. in ore geology in 1979 and PhD in Metallurgy in 1999. Subject of PhD thesis was HCFeCr process.

From 1979 and until she started as researcher in SINTEF in 2007, Eli worked in various mining and metallurgical companies. This includes Rana Gruber iron ore mine, Elkem Rana Ferrochromium plant, some of Elkems silicon plants and RDMN/Vale Mn-alloy plant in Norway.

Ian Cameron

Principal Metallurgist, Ferrous Hatch Ltd.

The steel industry and its related supply chain emit more greenhouse gases (GHG) than any other metal produced. Accounting for 7-9% of global GHG emissions, steel production is deemed a ‘hard-to-abate’ industry due its reliance on carbon to reduce iron ore to iron. Steel demand will grow significantly due to population growth, demands to build renewable energy systems, and a need for more resilient infrastructure.  The steel industry challenge is to reduce GHG emissions while increasing output by as much as a 30% over the next 30 years. A credible path to net zero GHG emissions is essential for access to the capital needed to convert current facilities to new green steel plants.
The iron ore and steel industries are exploring many technologies to develop pathways to net zero including advanced iron ore upgrading, steel scrap usage; process electrification; hydrogen and biomass reduction of iron ore; and carbon capture, utilization, and storage.  Starting from current steel industry GHG emission profiles, technology routes that enable deep GHG reductions will be described, including an update on technology readiness levels and commercialization timeframes.  Pathways to net zero by 2050 are possible; likely routes and key enabling technologies for the incumbent blast furnace-basic oxygen furnace (BF-BOF) route; the direct reduction ironmaking – electric arc furnace (DRI-EAF) route; and the scrap melting EAF steel producers will be presented.

Ian Cameron is the Principal Metallurgist, Ferrous at Hatch Ltd. He develops client-focused solutions to produce iron and steel starting from the basic raw materials. Ian has extensive international experience in ironmaking process technology, plant operations, and new technology implementation. His experience includes coke plant, pellet plant and blast furnace design and operations, assessing steel plant carbon footprints, and the implementation/impact of future ironmaking technologies that reduce greenhouse gas emissions. Ian is the lead author of a new book, “Blast Furnace Ironmaking, Analysis, Control and Optimization” where he and his co-authors outline a first principles approach to complete blast furnace heat and mass balances.

Ian holds Bachelor and Master’s degrees in metallurgical engineering from McGill University and is a Professional Engineer in Ontario.

Torben Edens

Director Aurubis AG

The deoxidation of copper or “poling” is the final step in the pyrometallurgical process of primary and secondary copper extraction. The deoxidation generates CO2 since gaseous and liquid hydrocarbons (natural gas) are the common choice for reducing agents. Previous energy and cost saving measures increased the efficiency of the process, but the inherent production of CO2 cannot be avoided. The use of hydrogen as a reductant may decarbonise a core process of copper production, which is a desirable target for the metal industry in general and Aurubis in particular.

The primary smelter in Hamburg runs two anode furnaces with a capacity of 270 t per batch each. From September to December 2021, the anode furnaces were provisionally supplied with hydrogen and 14 batches were poled using hydrogen. These experiments were designed to determine in full scale operational tests the properties of the poling with hydrogen in terms of efficiency and process control.

The average efficiency of poling with hydrogen was higher than poling with natural gas. The adjustment of the volume flows and the temperature control of the process was always controllable. The end point of the poling with hydrogen could be determined similarly to the poling with natural gas based on the temperature curve.

The tests showed the importance of nitrogen addition for stable jetting conditions where clogging of the tuyeres was a phenomenon observed when pure hydrogen was used. An important observation from the tests was that the efficiency of the reduction was not affected by the addition of nitrogen.

This paper will discuss in detail and share the learnings of full-scale polling tests in the Hamburg anode furnace and discuss requirements for its introduction into the daily production.

Since 2002, I have been working with Aurubis in various positions as director and plant manager both in copper primary smelter and in R&D.

Electrochemical Degradation of Multi-Component Materials


 

Jing Liu

Professor, University of Alberta

Cantor high-entropy alloys (HEA, the original equiatomic FeCoNiCrMn and its derivatives), are promising structural materials for high-temperature applications, and have the potential to replace Ni-base superalloys as the next generation high-temperature materials. Among the group of Cantor HEA, FeCoNiCrCu (H5C) shows the highest valence electron concentration (VEC), which favors the presence of two separated ductile FCC phases, resulting in excellent deformability and thermal stability. In recent years, H5C has been developed broadly to extend its applications for extreme service environments such as in the nuclear, turbine, and aerospace industries, wherein a high risk of high-temperature oxidation is involved. In this work, equiatomic H5C, a dual-phase FCC HEA, is chosen as the starting model alloy to investigate the temperature-dependent oxidation behavior of Cantor HEA in ambient atmosphere through both experimental and density-functional theory (DFT) calculating approaches. It is expected to construct a common model for predicting oxide scale evolution in support of designing and validating Cantor HEAs with good and selective oxidation performance at high temperatures. Oxidation experiments of the H5C HEA were conducted at 700, 800, and 900 °C, respectively. A range of techniques, such as X-ray diffraction (XRD), Scanning electron microscope (SEM), Focused ion beam (FIB) and Transmission electron microscopy (TEM), were used to determine the morphology, phase components, and compositions of the obtained oxidation scales. Diffusion coefficients of the principal elements in H5C as well as O were obtained through DFT calculations. Characteristic results showed that the oxide scales on H5C mainly consisted of three layers for all temperatures although the morphology and structure of the outmost layer were strongly dependent on temperature. It was found that the outmost layer in the oxide scale evolved from pure CuO to a mixture of CuO+Cr2O3 with increased temperature. Cu possessing the highest diffusion rate favored the fast formation of a pure island-shaped CuO scale from the Cu-rich FCC phase at 700 °C, which indicated a weak protective response. Cr2O3 grew outwards and formed a continuous CuO+Cr2O3 outmost layer when temperature gradually increased up to 900 °C, providing an improved protection from hot oxidation. Together this study suggested that the competition in oxidation activities and elemental diffusion coefficients across dual FCC phases determined the final oxide scales yielded on the H5C surface at different temperatures. In addition, mechanisms of the temperature-dependent oxidation of H5C HEA were discussed in detail from a comprehensive thermodynamics and kinetics perspective.

Dr. Jing Liu received her Ph.D. in 2015 from UBC. After that, she worked as a postdoctoral research fellow at UBC for three years and worked as a metallurgist in Kemetco Research Inc for one year. Currently, she is an assistant professor at the U of A. Her research interests include corrosion and materials degradation, electrochemistry, high entropy alloys, and materials characterization.

Symposium:
Light Metals for the Transportation Industry


 

Carsten Siemers

Senior Research Scientist Institute for Materials Science, Technische Universität Braunschweig

Titanium alloys combine outstanding mechanical properties with excellent corrosion resistance that make them desirable for challenging light-weight constructions in the transportation industry like fuselage frames or aircraft engine components. On the other hand, titanium production is energy-consuming and expensive, since the current method of extraction of titanium from the ores includes smelting, chlorination and reduction by magnesium (Kroll’s process). Hence, cost-reduction is one of the main driving factors for titanium research to broaden its field of application.

In this overview presentation, the conventional production route from titanium ore to semi-finished products and components is presented. This includes ore winning and processing, melting and remelting for ingot production, forging, casting, machining of (semi-finished) products and scrap recycling, all of which are discussed through several examples.

Additive manufacturing (AM) processes, such as powder-bed fusion (PBF), can help to increase titanium usage, since even complicated geometries can be directly produced without much material loss. On the other hand, rapid cooling and directional solidification result in anisotropic properties and martensitic or lamellar microstructures of the AM parts. In addition, defects like pores are always present in the as printed condition, which have a detrimental impact on the mechanical properties. These defects can only slightly be reduced by using a dedicated building strategy or by post-processing. The state-of-the-art in powder bed fusion and selected research activities are also discussed in this presentation.

Carsten Siemers started his research career on the machinability of Titanium alloys as an “Early Stage Researcher” in Braunschweig in 2000. In 2005, he secured a permanent position as a “Senior Research Scientist” at the University of Technology (TU) Braunschweig. Currently, he heads the Titanium Research Group of the Institute for Materials at the TU Braunschweig. Research in his group is focussed on the development of advanced Titanium alloys for several fields of applications like the aerospace, the medical and the automotive industries. This includes the identification of alloy compositions and alloy production as well as alloy characterisation and testing in laboratory and industrial scale. He has authored and co-authored more than 80 papers in the field of materials science and engineering with more than 450 citations. In 2012 Carsten Siemers has been elected chairman of the Titanium Technical Experts’ Committee of the German Materials Society (DGM), i.e. a liaison person between Academia and Titanium industry in Germany. This includes the position of the German representative in the international organizing committee of the Titanium World Conference.

Hani Henein

Professor University of Alberta

Aluminum alloys are heavily used within the transportation sector due to their excellent mechanical properties, high strength to weight ratio, corrosion resistance and high thermal conductivity. Cerium containing aluminum alloys have become a focus of interest for high temperature alloys. Al-Ce based alloys consist primarily of fcc aluminum and Al11Ce3 intermetallic. Due to the near zero solubility of cerium in fcc aluminum (less than 50 ppm at the eutectic temperature), the strengthening Al11Ce3 intermetallic is very stable against high temperature dissolution. Furthermore, while Cerium is the most abundant of the rare earth elements, it has yet to have any substantial high-volume use. It currently remains relatively inexpensive as an alloying element. In this work, containerless solidification of hypereutectic Al-20wt%Ce is carried out using ElectroMagnetic Levitation and Impulse Atomization. The effects of rapid solidification on the microstructures are analyzed using neutron diffraction, X-ray and electron microscopy and Electron Backscattered Diffraction.

After completing the MEng at McGill University (1975) and a PhD at UBC (1981), Hani took up a faculty appointment at Carnegie-Mellon University, Pittsburgh, PA. In 1989, he moved to the University of Alberta actively teaching and doing research on pipeline steels, metal-matrix composites and rapid solidification. He partners with industry in research and has extensive international collaborations. As part of his mentoring activities, Hani formulated an international work abroad program for undergraduates in several high quality engineering programs in Europe and Japan, placing over 80 students since 2002. He formulated in 2011 a Dual Degree Program with the Université de Lorraine. Amongst the distinctions he has received are five best paper awards, the prestigious Killam Research Fellowship, and the Metals Chemistry Award. He has been inducted Fellow of The Canadian Institute of Mining, Metallurgy and Petroleum (CIM), ASM International (ASM), the Canadian Academy of Engineers (CAE), The Minerals, Metals and materials Society (TMS) and the Institute of Materials, Minerals and Mining (IOM3). In service, Hani plays a leadership role in the profession as the 1998 MetSoc President, Past Editor of CMQ, the 2014 President of the Minerals, Metals and Materials Society (TMS) and the 2019 President of the American Institute of Mining, Metallurgical and Petroleum Engineers.

Processing of Critical Materials


John Goode

J.R. Goode and Associates

Decarbonization to limit climate change requires the replacement of fossil fuel by renewable energy resources, electrification of vehicles, and several other strategies.  The technologies that must be deployed consume critical materials including rare earth elements (REE), and in particular praseodymium, neodymium, terbium and dysprosium.  It is generally estimated that between 2022 and 2030 or 2031, the consumption of these elements will increase by a factor of two.  To put this into context, a deposit similar to Mountain Pass or Mt. Weld, and associated processing and separation facilities, must be commissioned every second year over the next eight years.  This paper reviews the characteristics of available rare earth sources, especially ore deposits, and attempts to identify those sources with the highest potential to deliver the required REE production.  

John Goode graduated from the Royal School of Mines, United Kingdom, in 1963, and joined Falconbridge, spending two years trouble-shooting the pyrrhotite roasters. This was followed by jobs at RTZ’s Avonmouth smelter in Rio Algom’s Elliot Lake uranium-rare earth plants and for Ore Sorters.

In 1976, Goode joined Kilborn Engineering where he spent 18 years, where he eventually became VP Mining and Metallurgy. In 1994, he joined Barrick and managed its China operations for the next four years.

On his return to Canada, he established a metallurgical consultancy which has undertaken gold, uranium, rare earth and other projects for Barrick, Placer, Iamgold, Avalon, Crystallex, Serra Verde, NRCan and others. Current assignments are located in Russia, Brazil and Canada.

Goode has co-organized CIM conferences, presented short courses, delivered 60 papers and is a peer reviewer. He has lectured at Ryerson University and is on a Canadian CSA/ISO committee drafting standards for the rare earths industry.
