Abstrakt: Conclusions 1.The existence of the effect of dynamic spheroidization of carbides observed previously on wedgeshaped samples was observed on massive samples of rectangular cross section in deformed steel at subcritical temperatures, and the effect of the formation of divorced pearlite during cooling in air of steel deformed at supercritical temperatures.2.Dynamic spheroidization and spheroidization rolling of steel at supercritical temperature ensure a higher wear resistance after quenching and low-temperature tempering as compared with spheroidization annealing.3.To obtain these effects the original (before warm rolling) preparation of the microstructure and additional tempering at 600° cannot be used.
