METHOD FOR PREDICTING REMAINING CREEP LIFE OF HEAT- AND PRESSURE-DEGRADED PRODUCT, AND STANDARD CURVE PREPARATION METHOD USING THIS PREDICTION METHOD

摘要

[Problem] Provided is a method for predicting the remaining creep life of a heat- and pressure-degraded product. Specifically, this method for predicting the remaining creep life is characterized by involving a step for calculating the length of the largest crack that has formed in the product, and a step for calculating the damage rate of the product from the obtained largest crack length, wherein the product has a bainite structure.
