Dr. Yiyu Wang joined ORNL in 2018. He earned his Ph.D. degree from the University of Alberta in 2017. His research focuses on physical metallurgy and welding metallurgy of structural materials, involving study of non-equilibrium phase transformations, materials characterization, testing and modeling of mechanical performance of welds. Dr. Wang is an active member of many professional associations, including the CWA, CIM, and AWS, by presenting technical papers in conferences and seminars. Dr. Wang has authored more than 30 peer-reviewed journal papers and 20 conference papers in topics of creep-resistant steel welding, pipeline integrity, failure analysis of welded pressure vessels, and diffusion bonding of dissimilar metals. He is a co-recipient of the 2017 W. H. Hobart Memorial Award and the 2018 and 2023 Warren F. Savage Memorial Award from the AWS, for the best Welding Journal papers in pipe welding and welding metallurgy.
