A revised interpretation of ultra-fast stress corrosion cracking experiments by Serebrinsky and Galvele

Reconsideration of data from stress corrosion cracking tests conducted at extreme strain rates on homogeneous noble-metal alloys leads to the conclusion that the data are more consistent with the film-induced ‘cleavage’ (in this case intergranular fracture) model than with the surface mobility model. At the highest strain rates, the data for several alloy systems are close to what would be expected from a single brittle event followed by ductile rupture. The opportunity is also taken to comment on some misconceptions regarding the predictions of the film-induced cleavage model, and more generally the correlation between dealloying and SCC in homogeneous noble-metal alloys.
