Microalloying Effects on Structure-Forming Processes during Hot Plastic Deformation

In this paper, we studied the kinetics of austenite grain growth during heating and the processes of dynamic and static recrystallization occurring in various modes of plastic deformation (reduction pattern, deformation temperature) of high-strength steels with various microalloying complexes. The performed studies allowed determining the thermal deformation conditions for the formation of a finely dispersed homogeneous structure of steel. Technological recommendations for the production of high-strength steels depending on their microalloying (vanadium and niobium) were developed.
