Dr. Alan Luo is Professor of Materials Science and Engineering and Professor of Integrated Systems Engineering (Manufacturing) at The Ohio State University (OSU). Dr. Luo is also Director of the Light Metals Research Laboratory (LMRL) at OSU. Prior to joining OSU in July 2013, Dr. Luo was a GM Technical Fellow at General Motors Global Research and Development Center (Warren, MI, USA) with 20 years of industrial R&D experience including 15 years at GM. Dr. Luo won two John M. Campbell Awards for his fundamental research, and three Charles L. McCuen Awards for research applications at GM. Prof. Luo has 15 patents and more than 170 technical publications in light metals, manufacturing and applications. Dr. Luo received his Ph.D. in Engineering Materials from the University of Windsor in Canada in 1993.
Prof. Luo is an elected Fellow of ASM (American Society of Materials) International and received the ASM Materials Science Research Silver Medal in 2008, SAE (Society for Automotive Engineers) International Forest R. McFarland Award in 2013, TMS (The Minerals, Metals & Materials Society) Brimacombe Medalist Award in 2013, and USCAR (United States Council for Automotive Research) Special Recognition Award in 2009. Dr. Luo’s research is also recognized by several Best Paper awards from TMS, SAE and AFS (American Foundry Society). Prof. Luo is presently the vice chair of TMS Light Metals Division and SAE Materials Division.
Advanced light metals (aluminum, magnesium and titanium alloys) are increasingly being used in the transportation, 3C and defense industries for weight reduction and structural efficiency. The mission of The Ohio State University (OSU) Light Metals Research Laboratory (LMRL) is to develop new alloys, manufacturing processes and Integrated Computational Materials Engineering (ICME) tools for lightweight structural applications. This seminar presents the development of new aluminum and magnesium alloys using classical and computational thermodynamics and the CALPHAD (CALculation of PHAse Diagrams) approach coupled with critical experimental validation. The talk will also summarize the latest process innovations in light metals manufacturing such as casting, forming and multi-material processing. Process simulation and multi-scale microstructure modeling techniques are used to develop and optimize these manufacturing processes. Lightweight structure designs often require multi-material solutions, using integrated computational materials engineering (ICME) tools. Examples are given in the design evolution of lightweight automotive powertrain, interior, chassis and body subsystems. Future research at OSU’s LMRL including magnesium, aluminum and titanium alloys will be discussed.
