Abstract：With material internal state varying, creep behavior keeps on changing during creep. A creep law which takes account of damage and hardening influence is proposed. Creep behavior of 12Cr1MoV steel is discussed. Analysis shows that creep rate keeps changing during creep. The secondary stage of creep is merely relative steady stage, and degree of relative steady and duration life fraction depend on applied stress. Different stresses cause the same damage state but different hardening state in conditions of the same exposure time fraction.
