摘要：
The influence of thermomechanical treatment conditions on the behavior of sparingly alloyed die steel with controlled austenitic transformation during operation (CATO) during deformation at 450-750 degrees C is studied. Austenization at 1150 degrees C, multiple tensile deformation at 450 degrees C, cooling to room temperature, and rapid heating up to 750 degrees C are shown to stabilize the state of hot working and provide the highest hardening of the steel at this temperature.
