The effect of hot plastic deformation on decomposition of supercooled austenite in some structural and die steels with different contents of carbon and alloying elements is investigated. It is shown that high-temperature plastic deformation accelerates the transformation of supercooled austenite by the diffusion mechanism and decelerates the development of bainitic transformations by raising the hardenability of the steels. The general laws of formation of mechanical properties under high-temperature thermomechanical treatment of structural and die steels after low- and high-temperature tempering are studied.
