Conclusions
-
1.
The carbide phase in complex-alloy die steel 8Kh4V2S2MF is appreciably broken up on increasing the temperature of electric heating for quenching from 1000 to 1200°C (a heating rate of 20 deg/sec in the region of the phase transformations).
-
2.
Electrothermal treatment ensures a finer carbide phase than heat treatment in accordance with the optimal regime with heating in a salt melt.
