Abstract: Complex applications in modern technology urgently call for advanced structural materials that are high strength and light-weight, and yet tolerant to damage from extreme temperature, particle radiation, or environmental exposure. To swiftly fulfill these emerging demanding material requirements, we must develop a multi-scale understanding of the relationship between processing, microstructure, and properties in metallic materials. Toward these goals, a modern High-Resolution Electron Backscatter Diffraction (HR- EBSD) technique that offers the capability to measure the deformation and microstructural evolution of material at the micro-scale is utilized. I will present our recent findings on how the macroscopic strength of magnesium alloys is dictated by local microstructure features such as barrier strength of specific grain boundaries to specific slip systems measured by HR-EBSD. I will conclude my talk by discussing how such an understanding can be implemented into multi-scale modeling tools to predict the deformation of the material and accelerate the advancement in the designing of the next generation of materials.

Bio: Bio: Mohsen Taheri Andani is a Mechanical Engineering Ph.D. candidate at the University of Michigan, Ann Arbor. He has received a MS in Materials Science and Engineering from the University of Michigan, Ann Arbor, and a MS in Mechanical Engineering from the University of Toledo. His research focuses on establishing the inter-relationship between processing, microstructure, and properties in structural metallic materials. His research brings together multi-scale, cutting-edge experimental and computational modeling tools to accelerate the design of future structural materials. Based on his research as a graduate student, he has co-authored 21 journal articles, including 9 as a first author. Mohsen has received several awards and honors for his dissertation research, including the “Richard and Eleanor Towner Prize for Outstanding Ph.D. Research” (by College of Engineering, University of Michigan), “Ephrahim Garcia Best Paper Award” (by ASME), and “Ivor K. McIvor Award for demonstrating excellence in research and scholarship in applied mechanics” (by College of Engineering, University of Michigan).
