Conclusions
-
1.
The magnitude and sign of residual stresses of the first kind vary several times both near the surface and in the volume of the specimen as a result of thermal cycling.
-
2.
Thermal cycling leads to variation in block dimensions and dislocation density.
-
3.
The maximum limited longevity of steel 3KhM3F is observed at the highest residual compressive stresses and dislocation density.
-
4.
Use of certain types of technological treatments (PME, HTMT, and their combinations) lead to an increase in specimen longevity; this enables us to suggest the promising nature of these methods of treatment for the hardening of hot-stamping dies.
