There is a huge interest from different industries including aerospace, marine, medical, automotive, and energy for light metals developed through additive manufacturing (AM) for optimum performance. These alloys will be used in extreme conditions of severe mechanical loadings (impact and cyclic), corrosive environments, and other harsh situations (e.g. radiation). Thus, developing additive manufacturing process parameters to successfully print these alloys can enhance the adoption of AM in different sectors. All current methods of AM including but not limited to laser/electron beam powder beam fusion, blown powder, wire and arc-related techniques, binder jetting, friction stir processes are of particular interest. The symposium also focuses on light metals developed through novel AM techniques, which are beyond the current beam technologies. Advanced characterization contributions including in-situ melt pool monitoring, radiography, electron microscopy, and etc. are also welcomed. The symposium chair invites researchers to discuss rapid solidification phenomena present in AM (experimental and numerical) and investigate concepts such as hot tearing, grain refinement, alloy design, and interface engineering. The use of advanced modeling techniques to redefine process parameter development and design for additive manufacturing including machine learning, topology optimization, and artificial intelligence is of importance.
