Abstract
The phenomena of hydrogen induced cracking (HIC) in 304 stainless steels was considered in a hydrogen pressure and stress corrosive atmosphere. Microstructures with chloride pits and stress corrosion cracks around the HIC were analyzed by SEM/EDS. Abnormal phase transformations induced by the hydrogen were analyzed using TEM and diffraction.

Abstract
Austenitic stainless steel SS304 is vulnerable to Cl atmosphere SCC (stress corrosion crack). In this study, SCC phenomena related to stress and corrosion composition were analyzed to identify the mechanism for SCC initiation and propagation in SS304. The microstructure and mechanical properties resulting from crack propagation were analyzed by OM,..... More

DOI: https://doi.org/10.3365/KJMM.2019.57.10.624

Abstract
High-Mn steels developed for offshore industries require good resistance to stress corrosion cracking (SCC) in seawater. Elements like Cr and N are often added to improve the resistance to SCC. In this study, the SCC behavior of Fe18Mn3Cr0.1N and Fe19Mn19Cr0.6N steels in artificial seawater was examined. Slow strain rate tests..... More

DOI: https://doi.org/10.3365/KJMM.2018.56.10.708

Abstract
For proper maintenance and inspection scheduling of aircraft, it is extremely important to measure the resistance to stress corrosion cracking (SCC) behavior of aluminum alloys used for aircraft structures. The SCC resistances of high-strength 7xxx-series aluminum alloys, including 7050-T7451, 7475-T7351 and 7140-T7451, were evaluated along longitudinal (L) and transverse (T)..... More
