A hysteretic loop correction (HLC) model was established by introducing the position and shape correction factors of hysteretic loop in early study (International Journal of Pressure Vessels and Piping, 86 (2009) 616-621) based on the testing data of two Ni-based super alloys of FGH95 and GH4169. This paper attempts to develop a general expression of the model to correlate the data of high-cycle fatigue, thermal-mechanical fatigue, and multi-axial fatigue. The form of the generalized hysteretic loop correction (GHLC) model is similar to the total strain equation just the coefficients are not constants but variables. The model shows more comprehensive applicability under different kinds of testing conditions and correspondingly applied to the life evaluation of a powder metallurgy (PM) disc of turbo engine. The results illustrate an agreement with linear damage accumulation model’s calculation and design life of the disc.
