This paper mainly studies the creep characteristic of nickel-base superalloy GH4169 under high temperature. From the perspective of modeling methods, based on the continuum damage mechanics, a creep life prediction model was proposed to predict the creep life of metal materials in both uniaxial stress state and multiaxial stress state, and experimental verification is done. Moreover, from the perspective of numerical analysis, it compares the test data with the analysis results obtained by the finite element analysis using Graham creep model, and the comparison result shows that numerical analysis results agree well with the experimental data.
