Advances in Solid-State Welding and Processing of Metallic Materials

This book covers the essential information needed to understand the latest developments of solid-state welding and processing of metallic materials, including physical metallurgy, production technologies, alloy development, compositing, post-processing, and joining methodologies.

Dr. R. Vaira Vignesh completed his undergraduate studies with a Bachelor’s degree in Mechanical Engineering (First Class with Distinction) at Karpagam College of Engineering, an autonomous institution affiliated with Anna University, Chennai. He holds the distinction of being the first and youngest scholar to embark on the doctoral program directly following his bachelor’s degree at Amrita Vishwa Vidyapeetham, where he earned a Ph.D. in the Faculty of Engineering for his significant research contributions to magnesium-based biodegradable implant materials. Dr. Vairam’s dedication and expertise have garnered him numerous accolades, including the Amrita Vishwa Vidyapeetham - Chancellor’s Publication Award for his outstanding work in the field of solid-state welding and processing of lightweight materials. He secured ＂Amrita Vishwa Vidyapeetham - Chancellor’s Collaborative Research Fellowship＂ to support collaborative research on ＂Development and indigenization of sustainable Bio-Lubricants for Automotives＂ with King Mongkut’s University of Technology, North Bangkok, Thailand. He presently holds the position of Assistant Professor (Senior Grade) within the Research Track in the Department of Mechanical Engineering, Amrita School of Engineering, Amrita Vishwa Vidyapeetham (Coimbatore Campus).

Dr. M. Govindaraju completed B.E in Metallurgical Engineering from Government College of Engineering, Salem, in the year 2001 and joined as Engineer at Nonferrous Materials Technology Development Center (NFTDC), Hyderabad in the same year. He served there for 15 years up to 2016 in various capacities including as Principal Scientist, before moving to Amrita Vishwa Vidyapeetham in July 2016 as Assistant Professor at Department of Mechanical Engineering. After joining in NFTDC, he completed M.Tech. (Welding) and Ph.D. from Indian Institute of Technology Madras subsequently. His Ph.D. thesis is on friction stir processing of magnesium alloys. He has industry and research exposure of over 23 years in various capacities. He has developed technologies for sheet brazing of automotive components and diffusion brazing of honeycomb structures which are transferred to industries. In addition, he is involved in building and indigenization of various process equipment, mainly high technology furnaces for processing of materials for Indian Space Research Organization, Bhabha Atomic Research Center, Defence Research and Development Organization and other national programs. He has completed 14 projects and 2 projects are ongoing; published more than 40 articles in international journals and conferences. He has indigenized more than 15 techniques / equipment for various applications in India.
