Conclusions
-
1.
Deformation (rolling) of quenched low-carbon medium-alloy steel improves the strength characteristics, with retention of good plasticity and ductility.
-
2.
The properties of martensite after deformation depend on the extent of development of the strain aging process.
-
3.
The development of the strain aging process during deformation of martensite and during subsequent heating depends on the rolling reduction, tempering before rolling, and the carbon content of the steel.
-
4.
The best combination of mechanical properties for steels susceptible to irreversible temper brittleness is attained by deformation of martensite tempered at low temperature with 15–20% rolling reduction.
