| Research Abstract |
In this study, the double-sample split-cell method was developed to investigate corrosion degradation under deformation. This method was applied to study the effect of applied stress on the initiation of localized corrosion of sensitized stainless steels. The results indicated that initiation of localized corrosion was enhanced by applying tensile stress or pre-strain. Furthermore, it was found that the morphology transition from a pit to cracks was observed when plastic strain was applied during growth of localized corrosion.
