Life prediction of hot work tool steels subjected to thermomechanical fatigue
Abstract
Surface of hot work tools is damaged by complex thermomechanical-wear-reacti-ve environment interactions. A thermomechanical fatigue (TMF) experiment using tubular spe cimens is developed. Tests are carried out under out-of-phase thermomechanical cycle. The mechanical strain is minimum (εm min) at upper temperature (Tmax) and it is maximum (εm max) at lower temperature (Tmin) of thermal cycle. The behaviour, the damage and the fatigue life of two tempered martensitic steels X38CrMoV5 (AISI H 11) and 55NiCrMoV8 (47 HRC) are assessed. The effect of Tmin and Tmax is examined. Softening is observed for both steels. For a given mechanical strain amplitude (εm = εm m ax-Em min), a drastic dependence on Tmax is demonstrated, while Tmin has less important effect. X38CrMoV5 has a better TMF life. Ductile fatigue striations are observed on the fracture surface of X38CrMoV5 specimens. The fracture surface of 55NiCrMoV8 specimens is covered by oxidation, making difficult to reveal the fatigue striations. Both oxide cracking and spalling are observed on the external surface of specimens. A phenomenological power law uniaxial model, based on the mechanical strain amplitude and Tmax, εm = K(Tmax).Nfα(Tm ax), is proposed to predict the life under non-isothermal fatigue solli citations. The life of some thermal fatigue tests is predicted within a factor of two to three. The capability of the model to predict the critical regions of an industrial hot work tool is reported.
