摘要：
The stress corrosion cracking (SCC) initiation behavior of FeCrAl alloy was studied through constant extension rate tensile (CERT) test in high temperature hydrogenated water. Compared with a nuclear-grade austenitic 304 stainless steel (SS), the FeCrAl alloy is much more resistant to SCC initiation. The difference in SCC resistance results from the different oxidation behaviors. 304 SS shows typical preferential intergranular oxidation (PIO) which can degrade the strength of grain boundary. In contrast, FeCrAl is immune to PIO and forms homogeneous nano-grained oxide layer. The original grain boundary vanishes after oxidation, thus is not a weak site for SCC initiation.
