The effects of electrochemical parameters in terms of electrochemical potential on stress corrosion cracking growth rates of au stenitic stainless steels in high temperature pure water are analyzed based on obtained experimental results and reported data. The effect of decreasing electrochemical potential is more significant in non-hardened sensitized and non-hardened stainless s teels than that in strain-hardened stainless steels, which is also supported by the results of Ni-base alloys and weld metals....

Effects of Electrochemical Parameters on SCC of Stainless Steels inSimulated BWR Environments

The effect of scratches on oxidation evolution of Alloy 600 was monitored by EIS in 290A°C simulated primary water. EIS result indicates that oxide film reached a stable condition until 7 days' immersion. The scratched Alloy 600 possessed almost the same evolution of oxide film with plain specimens. Anodic polarization was pe rformed to study combined effect of scratches and charged hydrogen. The anodic current changes of scratched A lloy 600 after hydrogen charging were not the simple superimposition bet...
