| 摘 要： | In this paper, the thermal fatigue test data in 3Cr2W8V steel are analyzed numerically. Then, on this basis a formula of thermal fatigue crack propagation rate with respect to stress intensiyt factor range is presented. Finally a dynamic equation of the control parameters for thermal fatigue crack propagationis derived according to evaluating the thermal strain relaxation property of the steel.
