Additive Manufacturing of High-Performance Metallic Materials

Professor Robert Pederson is professor in Engineering Materials and head of Division of Subtractive and Additive Manufacturing at University West. Robert has 20 years of experience within research and development of advanced metallic materials for aerospace and space applications. He received his PhD in 2004 in a project on titanium alloys in close collaboration with Volvo Aero Corporation (which became GKN Aerospace Engines Systems Sweden in 2012). Between 2004-2016, Robert worked at Volvo/GKN as research cluster leader, company specialist in materials technology, project leader, project manager, and responsible materials application engineer in a number of projects related with civilian aero engines as well as space rocket applications. In 2013 he became Associate Professor (Docent) at Chalmers University of Technology, and in 2015 he became Adjunct Professor at Luleå University of Technology. He has supervised 6 PhD students to doctors degree and is currently supervising 3 PhD students. The research work is focused on exploring and improving the understanding of the relationship between thermo-mechanical processing - microstructure - mechanical properties for titanium alloys and other metallic alloys and the key technologies of welding and additive manufacturing processes used by the aerospace and space industry. Professor Joel Andersson is a Professor in Materials Science and Head of Division of Welding Technology at University West and has extensive experience in superalloy metallurgy. Dr. Andersson has been responsible for research and development of high temperature materials from 2011-2015 at GKN Aerospace Engine Systems in Sweden, while having a part-time senior research position at Chalmers University of Technology in Gothenburg Sweden. Since the beginning of 2016, he has been at University West and currently also holds an adjunct professorship at University of Manitoba, Canada. He has co-authored around 100 papers in peer-reviewed journals and conference contributions and has up-to-date supervised 7 PhD students to doctors degree and is currently supervising 6 PhD students. Professor Shrikant Joshi has been at University West since Aug 2015, after long stints as a scientist in premier R&D institutions in India following his PhD at University of Idaho, USA in 1989. He has nearly 30 years of experience in fields spanning Surface Engineering, Laser Materials Processing and Additive Manufacturing. Shrikant has led numerous R&D projects that have culminated in many industrial applications, over a dozen patent applications and more than 185 publications in peer-reviewed journals. His current research interests focus on various powder and solution-based thermal spray techniques for varied applications including aerospace coatings, and on additive manufacturing with specific emphasis on post-treatment of Ni-based superalloys.
