Life Prediction and Evaluation of Fracture Toughness of a Cr-Mo Degraded Steel During Long Service
장기 사용 Cr-Mo강 열화재의 파괴 인성 평가와 수명예측
Abstract
It has been increasingly recognized that the safety analysis considering fracture mechanics is required of the pressure vessels made of 2 1/4 Cr-1Mo steel for safe operation due to temper-embrittlement during long term service. In this study, the fracture toughnesses of degraded and recovered 2 1/4 Cr-1Mo steels have been studied with J
