Dr. Somjeet Biswas specializes in mechanics of plastic deformation in ultra-fine and nanocrystalline materials through polycrystalline plasticity simulations with specific application in aerospace, automobile and degradable/permanent bio-medical implant applications. He has used microstructure engineering techniques like severe plastic deformation, thermo-mechanical processing and recrystallization to modify the morphological characteristics, texture and grain boundary to obtain ultra-fine grain metals and alloys that possesses both improved strength and ductility and hold seven patents, one copyright, and 44 publications. His thrust areas of research include development of advanced lightweight and high strength Mg, Ti, Al alloys and steels for automobiles, aircraft, bio-degradable and permanent bio-implants respectively. He and his team in the ‘Light Metals and Alloys Research Lab, MME, IITKGP’ is working on deciphering the effect slip/twin induced deformation behavior, dynamic recovery and recrystallization on evolution of dislocations, microstructure, texture and misorientation boundaries in order to improve specific properties based upon application.
