摘      要：The surface oxide film cracking behavior of Fe-30Ni-20Cr alloy under in-phase and out-of-phase synchronizing thermal cycling with mechanical cycling was *** oxide film cracking along the grain boundary under in-phase overlapping was creep predominant fracture *** induced slip lines preceding were accompanied by the surface oxide film cracking under Out-of phase,and the shear cracking was dominant *** mean stress could counteract a part of the tensile component of alternative stress,so as to delay the cracking process under in-phase,but positive mean stress overlapping the tensile alternative stress could accelerate the cycling cracking process under out-of-phase.
