Study on characteristic curves of creep-fatigue interaction on 12Cr1MoV steel

摘要

This paper states the experiment results of investigation of fatigue damage, creep damage and their interaction on 12Cr1MoV steel and welding joint. An envelop of the interaction between fatigue damage and creep damage which could be used in practice was first given in China. This envelop is compared with that of 2.25Cr1Mo steel given in ASME BPVC.
