摘　　要：研究了Cr5Mo合金钢在外加作用力时的高温氧化失效过程。对其在有不同应力作用时的高温氧化形貌、氧化反应速率等进行了试验分析,并与相同试验条件下无外加作用力时的Cr5Mo合金钢的高温氧化过程进行对比,从而发现了外加载荷作用力对Cr5Mo合金钢高温氧化失效的变化规律。The damage process of high temperature oxidation under tensile load had been experimentally researched on Cr5Mo alloy. The surface visages and reaction rates of high temperature oxidation under different Stress also had been researched in this paper. With comparing the experiment results of oxidation process under tensile load or without tensile load on Cr5Mo alloy, the exactly research conclusion about the law of high temperature oxidation invalidation under tensile load had been gotten on Cr5 Mo alloy.
