Abstract

The effect of hydrogen on stress corrosion cracking (SCC) of 2205 duplex stainless steel (DSS) with different microstructure in simulated deep-sea environments was studied through microstructure characterization, electrochemical measurements, hydrogen determination and slow strain rate tensile (SSRT) tests. Hydrogen degrades corrosion and SCC resistance by penetrating into matrix, weakening passive film and accelerating anodic dissolution (AD). Therefore, SCC is controlled by hydrogen embrittlement (HE) and hydrogen-facilitated anodic dissolution (HFAD). Microstructure has a great impact on SCC, and quenched DSSs are more SCC susceptible due to coarser grains, unbalanced partition of two constitutional phases, brittle precipitates and higher defect density.
