Good Agreement

Based on the creep test results of T91/12Cr1MoV dissimilar welded joint at different conditions, the creep curves of this dissimilar welded joint were established by modified θ projection concept. Low stress creep life was predicted by this curve and the established creep curve shows a good agreement with the experimental data. For computation, Larson-Miller parameters method was also used in creep life forecasting of T91/12Cr1MoV dissimilar welded joint. The resu lt showed that the modified θ projection concept was more accurately in predicting the creep life than Larson-Miller parameters method in allusion to T91/12Cr1MoV dissimilar welded joint.

Abstract This paper deals with the creep characteristics of the aircraft turbine disc material of nickel-base superalloy GH4169 under high temperature. From the perspective of continuum damage mechanics, a new creep life prediction model is proposed to predict the creep life of metallic materials under both uniaxial and multiaxial stress states. The creep test data of GH4169 under different loading conditions are used to demonstrate the proposed model. Moreover, from the perspective of numerical simulation, the test data with analysis results obtained by using the finite element analysis based on Graham creep model is carried out for comparison. The results show that numerical analysis results are in good agreement with experimental data. By incorporating the numerical analysis and continuum damage mechanics, it provides an effective way to accurately describe the creep damage process of GH4169.
