A creep–fatigue crack growth model containing temperature and interactive effects

Abstract A trinomial superposition model containing a temperature parameter and accounting for creep–fatigue interactive effect for predicting creep–fatigue crack growth rates is proposed in this paper. Items and parameters in the model are investigated via fatigue crack growth experiments with 0 s and 90 s dwell time at different elevated temperatures on a nickel-based powder metallurgy superalloy FGH97. The results indicate a good capability of the proposed model in correlating the crack growth rate with creep–fatigue interactive effect. The model is also validated by available test results of Alloy 718 at 550 °C and 650 °C with various dwell times.
