The susceptibility to stress corrosion cracking (SCC) of two candidate container materials for the multi-barrier nuclear waste package was evaluated by using wedge-loaded and precracked
double-cantilever-beam (DCB) specimens in a deaerated 90°C acidic brine (pH = 2.7). Materials tested include Alloy 22 (UNS N06022) and Ti Grade-12 (UNS R53400). Duplicate samples of each material were loaded at different initial stress-intensity factor...
