Research Abstract

The evaluation of a crack tip of stress-corrosion cracking on the stainless steel was carried out by a positron microprobe. The vacancy-type defects are introduced before crack grows. Vacancy type defects may be generated as crack precursor. Vacancy defects were identified as monovacancies. It was found that plastic deformation near the crack tip is one the candidate for the source of such vacancy defects.
