Abstract This article describes the slow strain-rate stress corrosion cracking (SCC) of Admiralty brass sheet in an aqueous 0.1M CuSO/sub 4/ solution that is studied over a range of strain paths form uniaxial to equibiaxial tension. The average crack growth velocity is independent of deformation path. It is concluded that the mechanism of transgranular SCC in this system does not depend on multiaxial strain path for the range of stress states examined. The fracture strain data show that the slow strain-rate SCC of the brass sheet results in ductility losses which are larger in equibiaxial tension than in either uniaxial or plane strain tension.
