Abstract

Abstract

Aiming at the problem of creep damage assessment for 12Cr1MoV steel used in the main steam pipeline of in-service power plants during long-term operation, a creep damage evaluation and remaining life prediction method based on micro-specimen high-temperature pneumatic bulging test is proposed. Creep interruption tests under different stress levels were carried out to obtain specimens with different damage states, and the residual mechanical properties of the material were tested by high-temperature pneumatic bulging technology via micro-specimens. Based on the obtained mechanical properties, creep damage evaluation parameters were constructed and coupled as internal variables to the Larson-Miller parameter model, and a prediction model for residual creep life was further established. The test results show that this method can effectively characterize the creep damage degree of the material, and the predicted residual life by the model is in good agreement with the tested results, with all predicted results within 1.5 times scatter band.
