概要
Fatigue damage evaluation for austenitic stainless steel SUS304 was performed by electromagnetic non-destructive testings using magnetoresista nce(MR) and eddy current technique(ECT) sensors. The fatigue damage and fatigue crack could be detected by MR and ECT sensors. Especially, by M R sensors, changes in fatigue crack of notched specimens were measured, and by ECT sensors fatigue damage of martensitic transformation of pla in specimens was evaluated. These results were explained by the difference of martensite distriburtion between the plain and notched specimens.
