Notes:
Both EBSD and AFM methods were used to investigate the active slip systems andfatigue crack initiation behavior in face-centered cubic polycrystalline metal, austenitic stainlesssteel, SUS316NG, under cyclic torsional loading. Most active slip planes are the primary slip planeshaving the largest Schmid factor. Grains with slip band cracks or transcrystalline cracks have largerTaylor's factors. On the basis of EBSD and AFM observations, h, the depth of intrusion vertical tothe surface, S, and the component of the slip displacement perpendicular to the surface trace, SB,showed a sharp increase at the onset of crack initiation. The critical value of SB at crack initiationwas 170 nm
