Abstract: 

Following a brief description of our Ohio Center for Laser Shock Processing for Advanced Materials and Devices and its activities, I will present results of our recent work on phase transformations, microstructure and properties of additive laser powder bed fusion processed Co-Cr-Mo and IN625 alloys and solid-state additive friction stir processed nickel-base alloys. The role of prior microstructure and defects on mechanisms governing evolution of solid-state phase transformations, microstructure and properties will be discussed. The effects of advanced mechanical surface treatments on microstructure, residual stress and mechanical properties, including fatigue will also be presented and discussed.

Biography: 

Dr. Vijay K. Vasudevan is presently Herman Schneider Professor of Materials Science and Engineering in the Department of Mechanical and Materials Engineering at the University of Cincinnati (UC), Cincinnati, OH. He received his B.Tech. in Metallurgical Engineering in 1979 from the Indian Institute of Technology, Kharagpur, and his Ph.D. (1986) in Materials Science and Engineering from the University of Tennessee-Knoxville. He then joined the University of Illinois at Urbana-Champaign, initially as a Postdoctoral Research Associate, later becoming a Research Assistant Professor. In 1988 he joined the faculty at UC as an Assistant Professor, attaining his present rank of Professor in 1998. During this time, his research group has been actively involved in fundamental work on physical metallurgy, phase transformations, microstructural evolution, advanced mechanical surface treatments, mechanical behavior (creep, fatigue), deformation/fracture, corrosion and stress corrosion cracking mechanisms, structure-property relations and electron microscopy of advanced metallic alloys and intermetallics. Prof. Vasudevan has served as major advisor for >100 undergraduate, 29 M.S. and 18 Phd students and 9 postdoctoral research scholars, edited one book; published over 186 refereed technical articles; delivered over 300 presentations, including 92 invited talks; and received awards for excellence in teaching, service and research, including the Fulbright Senior Scholar Award, Japan Society for the Promotion of Science Fellowship at Kyoto and Tohoku University in Japan, the Sigma Xi Young Investigator Award for Scientific Research, Champion H. Mathewson Medal from TMS for the most noteworthy contribution to metallurgical science, Neil Wandmacher Award for Teaching Excellence and Distinguished Researcher Award from the College of Engineering at UC, and several best poster paper awards at national/international conferences. He is a member of ASMI and TMS, has served as past Chairman of the ASMI-TMS Phase Transformations and Structures Committees and currently serves as a member of the Board of Review for Metallurgical and Materials Transactions and as reviewer for many journals and federal agencies. He is also actively involved in student education, curricular and mentoring activities.
