Thermal history evaluation method for heat-resistant members and thermal history evaluation device

摘要

PROBLEM TO BE SOLVED: To evaluate a thermal history of a heat-resistant member simply and with good accuracy regardless of the configuration of an evaluation target. SOLUTION: In the thermal history evaluation method, a plurality of first temperature detecting members capable of detecting a temperature based on a change in properties due to thermal aging are installed in an inspection target portion specified as a heat resistant member. The thermal history of the heat-resistant member is obtained based on the property change of the plurality of first temperature detecting members. [Selection diagram] Fig. 2
