Abstract
In order to prevent stress corrosion cracking (SCC) in stainless steel used as a structural material for various industrial plants, it is important to reveal the propagation behavior of the crack. For the purpose of pursuing the quantitative time dependence of developing cracks, the changes in both the depth and the aperture of identical crack with the SCC time was clarified by using X-ray computed tomography (XCT). The resulting outcomes contribute to elucidation of the SCC behavior as well as technological improvements on life prediction and materials design.
