Abstract

Summary form only given. It is very important to determine fatigue damage of austenitic stainless steel such as SUS304 used in structural components to prevent accidents. The amount of fatigue damage and the remaining service life are important parameters to know. In order to access the remaining service life, the perpendicular residual magnetization method using a thin-film fluxgate magnetic sensor is applied. We discuss the amount of fatigue damage, the evaluation of the amount of martensitic phase in austenitic stainless steel and the relationship between growth of a crack and the residual magnetization.
