Solid-State Metal Additive Manufacturing Physics, Processes, Mechanical Properties, and Applications

Hang Yu obtained his Ph.D. degree in materials science and engineering from MIT in 2013 and B.S. degree in physics from Peking University in 2007, and is currently an assistant professor in the Department of Materials Science and Engineering and a key member of the Advanced Manufacturing Team at Virginia Tech. Dr. Yu's research has been focused on solid-state metal additive manufacturing using additive friction stir deposition, which is an emerging large-scale technology giving rise to forging mechanical properties in the as-printed state.

Nihan Tuncer, Ph.D., completed her BS in Metallurgical and Materials Engineering in Middle East Technical University in 2002 and her MSc and PhD in Anadolu University in 2011 in Turkey. Following her PhD, she worked as a visiting scientist in Forschungszentrum Juelich IEK-1 in Germany on metal injection molding of porous Titanium implants. She conducted her postdoctoral research at MIT between 2012-2016 on Cu-based shape memory alloys. She has been working at Desktop Metal since 2016 as a Principal Scientist, where she authored a number of papers and patents. Her expertise includes powder metallurgy of steel, titanium, hard metals, nickel-based alloys, ceramic-metal composites, shape memory alloys, porous metals, microstructure development and mechanical properties of materials.

Zhili Feng obtained his Ph.D. degree in welding engineering from Ohio State University, and M.S. degree in mechanical engineering and B.S. degree in mechanical engineering both from Tsinghua University. Dr. Zhili Feng currently leads the Materials Joining Group and is a Distinguished R&D Staff of Oak Ridge National Laboratory. He is also a Joint Faculty of University of Tennessee, Knoxville. Dr. Feng's research covers various aspects of thermal-mechanical-metallurgical behaviors of materials in materials joining. He has broad interactions with industry and demonstrated experience in solving critical industry problems.
