Abstract

In applying eddy current testing to evaluation of fatigue cracks in austenite stainless steels, various influential factors are needed to be considered, such as martensite transformation of austenitic phase, crack closure, and oxide formation between crack faces, and so on. In this study, influential factors of heating of fatigue cracks in type 316 austenitic stainless steels are evaluated through experimental and numerical analysis. Signal phase shift and amplitude decrease by heating is systematically discussed.
