Fig.9 Stress corrosion crack initiation in the polished (a) and machined (b) surfaces of a warm-forged 304L stainless steel during SSRT test (Inset in Fig.9b shows the magnified image of rectangle area); a crack propagated transgranularly (c) and a crack branched and then propagated both intergranularly and transgranularly after penetrating beyond the topmost ultrafine-grained layer (d)[32]
