摘要:

模拟了海工结构的2205双相不锈钢钢筋 (A-DSS和B-DSS) 在人工海水中不同条件下的服役行为。通过D-S双电解池氢渗透技术测试了氢在两种钢筋中的扩散行为。通过慢应变速率拉伸实验，结合SEM观察，研究了钢筋在空气以及人工海水中的拉伸断裂行为，分析了阴极极化对断裂行为的影响。结果表明，氢在A-DSS和B-DSS两种钢筋中的扩散系数D分别为2.36×10^-10和2.31×10^-10 cm²/s。当A-DSS和B-DSS在人工海水中外加阴极极化电位分别为-800和-700 mV (SCE) 时，两种钢筋的环境断裂敏感性最低。利用SEM观察了在外加电位下断裂试样的表面形貌，可观察到表面裂纹在铁素体相中萌生并扩展，终止于奥氏体相或两相界面。

Abstract：

The hydrogen-induced cracking behavior of a new-designed duplex stainless steel 2205 (including its two-subtypes A-DSS and B-DSS) used for marine structures in artificial seawater was investigated by means of slow strain rate test (SSRT), mechanical test and scanning electron microscope. While the hydrogen permeation behavior of A-DSS and B-DSS was studied by Devanathan-Stachurski's hydrogen permeation technique. The results showed that the hydrogen diffusion coefficients for A-DSS and B-DSS were 2.36×10^-10 and 2.31×10^-10 cm²/s, respectively. A-DSS and B-DSS exhibited the lowest susceptibilities to environment induced fracture when the applied cathodic potentials were -800 and -700 mV (SCE), respectively. Correspondingly, SEM observations of the fracture surface of the above two steels showed that cracks initiated in ferrite phase, and were arrested by austenite phase or interface boundaries of ferrite/austenite.

Key words： 2205 duplex stainless steel cathodic polarized hydrogen embrittlement crack initiation
