Thermal mechanical cyclic strain tests were carried out under in-phase and out-of-phase conditions on a Nickel-base Super-alloy GH4133 in the temperature range of 571-823℃. Based on analyzing the present models of TMF (thermal mechanical fatigue) life prediction, a new model for predicting nickel-base superalloy TMF lifetime was proposed. TMF life of superalloy GH4133 was calculated accurately based on the new model. Experimental TMF life has been compared with the calculated results and all results fall in the scatter band of 1.5. The calculating results show that the new model is not only simple, but also precise. This model will play great roles in life prediction of the metal materials and the engineering components subjected to non-isothermal service conditions.
