Prof. Rajiv Mishra (Ph.D. in Metallurgy from University of Sheffield) is a Regents Professor at the University of North Texas and founder of Optimus Alloys LLC. He is a Fellow of ASM International. He is a past-chair of the Structural Materials Division of TMS and served on the TMS Board of Directors (2013-16). He has authored/co-authored more than 450 papers in peer-reviewed journals and proceedings and is principal inventor of four U.S. patents. His current Google Scholar h-index is 95 and his papers have been cited more than 43000 times. He has co-authored three books; (1) Friction Stir Welding and Processing, (2) Metallurgy and Design of Alloys with Hierarchical Microstructures, (3) High Entropy Materials: Processing, Properties, and Applications. He has edited or co-edited fifteen TMS conference proceedings. He was an associate editor of Journal of Materials Processing Technology and is the founding editor of a short book series on Friction Stir Welding and Processing published by Elsevier and has co-authored seven short books in this series. He is a recipient of TMS-SMD Distinguished Scientist Award in 2020 and TMS-MPMD Distinguished Scientist Award in 2024. He is an adjunct professor in the department of Materials Science and Engineering at North Carolina State University. Most recently, he has founded Optimus Alloys LLC for commercialization of research efforts and serves as the Chief Scientific Advisor. Optimus Alloys is focused on process-specific alloy design for additive manufacturing of high-performance components.Harpreet Sidhar has been serving as a graduate research assistant for the past four years in the Dept. of Materials Science and Engineering, University of North Texas. His research has included Friction stir welding and characterization of: various Al-Cu-Mg-Li alloys; Al-Mg-Li alloy; and 7050-T7451 Al alloy; as well as studying dissimilar alloy friction stir welding of 2XXX and 7XXX alloys, as well dissimilar metal friction stir welding of HSLA 65 steel and aluminum 5083 alloy and dissimilar metal lap welding of aluminum 6022 and steel using friction stir scribe technology. Harpreet has presented the following papers at the following Conferences: Friction Stir Welding and Processing VII, 2013 TMS Annual Meeting & Exhibition; Aluminum Alloys: Development, Characterization and Applications, 2014 TMS Annual Meeting & Exhibition and Joining Dissimilar Materials for Energy and Mass Optimization for the Transportation Industry, Materials Science & Technology.
