摘要：

There has been considerable interest in the development of continuum damage (CDM) mechanism based model for creep life predictions of 9CrMoNbV steel. It is reported that the steel has high dislocation density in normalized and tempered condition whereas with creep exposure it goes down significantly. The paper examines one of the recent models and attempts to incorporate this as an additional damage parameter. This has resulted in much better prediction of creep stain time plots for this steel.
