Description

The influence of dynamic ageing on heat resistance of martensitic chromium steel type 13Kh11N2B2MF (EhI 961) is considered. Two different schemes of steel stress ageing were used: holding at heat (560 deg C) under constant stress; initial stress is relaxing due to difference in rigidity of speeimen and testing machine. It is revealed that the loading according to the latter scheme has a positive effect on stability of ultimate strength, microhardness and heat resistance of aged steel type 13Kh11N2B2MF. Hardening mechanisms and kinetics are discussed
