摘要：
In the present study, in order to evaluate the effect of oxidation effect on the creep-fatigue crack growth for 30Cr1Mo1V steel, fatigue crack growth (FCG) rates, creep-fatigue crack growth (CFCG) rates had been measured at room temperature, 540 degrees C and 650 degrees C in air and in argon environment with different load frequencies and waveshape. The results showed that temperature has determined effect on FCG rates. At a given temperature, the environments and creep exerted pronounced influence on the fatigue resistance at low frequency. When the hold time periods in cyclic loading exceeded 360s, more serious influence on the CFCG rates could be observed.
