Figs. 8 and 11 show the stress corrosion cracking fracture surfaces of cold worked austenitic stainless steel in high temperature water. The morphology of the SCC zone in the 316 is nearly 100% intergranular cracking while the 316L specimen shows predominantly intergranular cracking accompanied by some transgranularracking (Fig. 11). The EBSD results on the crack tip of the 316L specimen is shown in Fig. 12(c). The cracks on 316L specimen are not strictly along the grain boundary; the crack propagates transgranularly through some grains. Intergranular cracking was found to occur preferentially along random (high energy) grain boundaries; cracking along coincidence site lattice (CSL) boundaries was not found, consistent with previous studies [23].
