Creep Life Prediction of T91/12Cr1MoV Dissimilar Welded Joint

摘要

Based on the creep test results of T91/12CrlMoV 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 T91/12CrlMoV dissimilar welded joint.The resu It showed that the modified θ projection concept was more accurately in predicting the creep life than Larson-Miller parameters method in allusion to T91/12Crl MoV dissimilar welded joint.
