Fig.5. Schmidt factor distributions of grains in the nuclear grade 304 stainless steel (The low and high categories each contain 50% of the total grain population) (a), and plots of the co-dependence of irradiation assisted SCC (IASCC) cracking propensity on Schmidt factor pair type (LL—a grain boundary adjacent to two grains with low Schmid factors, LH—a grain boundary adjacent to a low and high Schmid factor, HH—a grain boundary adjacent to two grains with high Schmid factors, GBs—grain boundaries) (b)
