| 摘 要： | 采用慢应变速率拉伸（SSRT）试验方法，研究了FeCrAl铁素体不锈钢在偏离压水堆正常工况下的应力腐蚀行为。结果表明，在含有微量Cu2+与Cl-的高温水介质中，应变速率为2×10-7s-1时，FeCrAl铁素体不锈钢将发生显著的应力腐蚀开裂；其在含Cu2+和Cl-的高温水介质中的应力腐蚀开裂主要由点蚀导致。

| Abstract: | Stress corrosion behavior of FeCrAl ferrite stainless steel under PWR water deviation condition was investigated by slow strain rate tensile (SSRT) tests. The results show that FeCrAl ferrite stainless steel is subject to stress corrosion cracking (SCC) at strain rate of 2×10-7s-1, with the co-exist of Cu2+ and Cl- in water. SCC of FeCrAl ferrite stainless steel in high temperature water containing Cu2+ and Cl- is considered to result from pitting corrosion. |
