Creep damage evaluation method of tempered martensite steel

摘要

PPROBLEM TO BE SOLVED: To provide a method for evaluating the high temperature damage of heat-resistant steel capable of evaluating the creep damage of heat-resistant steel such as annealed martensite steel or the like. PSOLUTION: In the method for evaluating the creep damage of annealed martensite steel, it is evaluated that the life of the annealed martensite steel becomes short as the pattern quality of an electron beam back scattering image becomes high.
