Abstract
To control stress corrosion cracking (SCC) of stainless steel used in marine and coastal environments, it is important to clarify its spatial progress and time dependence on its initiation and propagation. In order to analyze initiation and propagation behavior of SCC in three dimensional (3D) view, SCC of stainless steel in the presence of chloride was observed for the first time in the world by using micro focus X-ray computed tomography (CT) of highly general use. The two and three dimensional information about initiation and propagation of SCC in stainless steel was obtained with this technique more easily than with a conventional way.
