Abstract

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.
