Research aera

Microstructural Engineering of SteelsThe department is scientifically orientated on theory of microstructure development in steels during thermal and thermo-deformation treatment processes. Investigation is related with grain boundary motion phenomena, thermal and deformation activated grain growth processes, kinetics of microstructure development, interaction of grain boundary with secondary phases and alloying elements, study of restoration processes (dynamic and static recovery, recrystallization after hot and cold rolling processes). An attention is paid to plastometric simulation of thermal-deformation processes and their interpretation by means of substructure change, analysis of selective nucleation and texture development during grain growth. A novel technology rout for texture and microstructure control in multi-layered steels is also deal of the investigation. The low carbon steels (deep-drawing, electro-technical, multifunctional, etc) are scientific orientation of the department.
