Abstract

The α↔γ- phase transformation, kinetics of bainite martensite transformation, changes of the structure and microhardness after high-speed heating and cooling of steels 40X was studied by high-speed X-ray apparatus. The microstresses levels, depending on the degree of deformation and after high-speed heating for steels 20 and 40X was definite.
