Description

Dealloying behaviour of Alloy 800 is investigated with respect to the dealloying-based SCC mechanism. Nanoporous layers were found in Alloy 800 exposed to 50 % NaOH at 280°C. Stressed C-rings showed massive crack propagation accompanied by nanoporosity evolution. The dealloyed layer analyzed is not the one that causes SCC, which is believed to be a much finer porous structure of nm dimensions. EDS point analysis performed on the cross-section of a dealloyed Alloy 800 layer showed depletion for Fe, Cr and increase in Ni content. (author)
