Abstract

Recent studies have shown that low ductility and brittle fracture in intermetallics are caused not only by intrinsic factors (such as lack of sufficient deformation modes, poor cleavage strength, etc.) but also by extrinsic factors. Environmental degradation, an extrinsic factor, is found to be a major cause of brittle fracture in many ordered intermetallics, particularly those with high crystal symmetries (i.e., cubic Ll2, and B2 and hexagonal DO19).
