Summary
Results are reported on the effects of various heat-treatment modes on the strength, plasticity, and short-time cracking resistance characteristics (KIc) for the torsion in 45KhN2MFA-Sh steel. The cyclic cracking resistances have been compared for test temperatures of 20 and 200°C for 45KhN2MFA-Sh and 50Kh3N2M2FA-Sh steels following various modes of heat treatment. The microfractographic aspects of cracking resistance in these high-tensile steels are considered.
