Abstract The tendency of glassy Fe-40Ni-14P-6B to stress corrosion cracking (SCC and hydrogen embrittlement (HE) in aqueous acidic media was investigated. Cathodically polarized, elastically stressed specimens failed in 1 M MCl by HE, as did those immersed in aqueous polythionic acid at the free corrosion potential. Similar specimens immersed in aqueous FeCl3 at the free corrosion potential failed by SCC, as did those anodically polarized in 1 M HCl. The FeCl3 specimens were covered with an iron oxide film, and selective leaching of nickel from pits and cracks was observed. The remarkable cracking patterns observed in aqueous FeCl3 reflect the isotropic, grain -free nature of the glassy alloy surface, and are thought to throw some light upon the internal stress profile of this interesting material.
