Microscopic fractography of the upper half part of an initially-fractured specimen rinsing in acetone and cleaning in deionized water. a The IG- mixed TGSCC. b The SCC cracks, the cleavage facets and the pits. c The slip bands during the IGSCC at the high stress level. It is apparent that no ductile dimples presented on the fracture surfaces.
