Based on modified θ projection method, creep experiments were carried out on GH4169 superalloy under different temperature and stress conditions,the creep data under different parameters were obtained and corresponding creep curves were drawn.The modified θ projection method was used to perform nonlinear fitting of the obtained experimental curve,and creep equations related to temperature and stress were established.The creep life curve of GH4169 superalloy is verified by the creep equations,and the results are in good agreement,so as to reach the effect of creep life prediction.
