AbstractFor safe use of the equipments in power plants, creep life prediction of the material served at high temperature is an important issue. With the purpose of the existing problems in overestimation of creep strengths, it is essential to analyze the creep mechanism and the creep damage to material in serving. In the present work, through analysis on creep curves of the T/P91 thermal resistant steel served in the super critical steam conditioned thermal power plants, the creep mechanism and the creep damage of T/P91 steel during creeping at 600 degrees C were discussed, and CDM (continuum damage mechanics) model established based on the physical nature was used to simulate the creep curves of T/P91 steel under high stresses. The modeled creep curves are good in agreement with the experimental data.
