Abstract

The stress corrosion cracking (SCC) behavior and mechanism of Fe-Mn-Al-C-Ni high specific strength steel (HSSS) in the marine atmospheric environment have been studied through gas medium mechanical-electrochemical testing apparatus. Results show that local anodic dissolution and hydrogen enrichment caused by the micro-galvanic effect between B2 phase and austenite γ matrix in HSSS are the main reasons for the preferential SCC initiation and propagation from phase boundaries. However, the SCC sensitivity can be greatly reduced under the premise of ensuring high comprehensive performance via optimizing the heat treatment process, which can provide the research foundation and ideas for the anti-SCC design of HSSS.
