Conclusions
-
1.
Hardening of sample 1 after deformation at 1000\dg and 500\dgC and at 1000–300\dgC was attained as the result of martensitic transformation caused by the subsequent cooling.
Hardening of sample 2 and 3 was attained by martensitic transformation in the process of plastic deformation at room temperature and −196°C.
-
2.
After hardening and tempering at 500\dgC, the steel has high strength (176–186 kg/mm2) with satisfactory ductility (6–10%).
