Dr. Sergey Zherebtsov is the Head of the Department of Materials Science and Technology at the Belgorod State University, Russia. His research areas relate to the Formation of ultrafine-grain microstructure in titanium and titanium alloys via warm large plastic working, as well as extensive TEM/SEM/EBSD studies of structural changes resulting in grain refinement during large strain deformation; effect of plastic working on evolution of interphase and grain boundaries and evaluation of mechanical properties of ultrafine grained metals and alloys.
