摘要：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. © (2013) Trans Tech Publications, Switzerland.
