Evaluation of J$_lc$ and T$_mat$ of aged 1Cr-1Mo-0.25V steel at elevated temperature
시효열화시킨 1Cr-1Mo-0.25V 강의 고온에서의 J$_lc$ 및 T$_mat$ 의 평가
Abstract
When crack are detected in aged turbine rotors of power plants, information on fracture resistance of the aged material at operating temperature is needed for determination of critical loading condition and residual life of the turbine. In this study, fracture toughness (J
