Metallurgy and Design of Alloys with Hierarchical Microstructures

Dr. Krishnan K. Sankaran is an Adjunct Instructor in the Department of Mechanical Engineering and Materials Science, Washington University in St. Louis, where he teaches a graduate level course titled “Metallurgy and Design of Alloys”. Dr. Sankaran specializes in aerospace materials and processes and retired as a Senior Technical Fellow from The Boeing Company in 2014. He received his Ph.D. in Metallurgy from the Massachusetts Institute of Technology in 1978. He has many publications and US and European patents. He has been an adjunct professor of materials science and engineering at the Missouri Institute of Science & Technology, Rolla, MO. He was a member of the Research Board and the Council of The Welding Institute, UK. He is a Fellow of the Academy of Science of St. Louis and a member of AIAA, ASM and TMS. In 2012, he was elected as Honorary Member of the Indian Institute of Metals for his distinguished services and significant contributions to the metallurgical profession and research. Rajiv S. Mishra is a professor in the Department of Materials Science and Engineering, and Site Director, NSF IUCRC for Friction Stir Processing, at the University of North Texas. Dr. Mishra’s publication record includes 255 papers. Out of these, 10 of his papers have more than 100 citations. He has many ‘firsts’ in the field of friction stir welding and processing. He co-authored the first review paper (2005), co-edited the first book on the subject (2007), edited/co-edited seven TMS symposium proceedings, and served as guest editor for Viewpoint Set in Scripta Materialia (2008). He also has three patents in this field. He published the first paper on friction stir processing (2000) as a microstructural modification tool. Satyam Suwas is Professor and Chairman in the Department of Materials Engineering at the Indian Institute of Science in Bangalore, India. His research interests include processing-texture relationship, light alloys, deformation and thermo-mechanical processing, and microstructural-mechanical property correlation. He was a 2019 Elected Fellow of both the Indian National Academy of Engineering (INAE) and the Electron Microscope Society of India (EMSI).
