Adopting the classical critical plane damage method coupling fatigue-creep life models with adequate technique modification, the life predications of ZSGH4169 superalloy at 650℃and DZ125 superalloy at 980℃ were investigated to compare the predication accuracies of the five kinds of fatigue-creep life models, i.e. based on Walls, Ccb, Swt, Glk and Fin. The results of typical examples show that the fatigue-creep model based on Walls is the best for ZSGH4169 superalloy at 650℃,and the predicted life falls within ±3 scatter band of the test data, while the fatigue-creep model based on Glk is the best for DZ125 superalloy at 980℃, and the predicted life falls within ±2.5 scatter band of the test data.
