Fig.4 Orientation dependence of deformed microstructure in metals: (a) orientation dependence of dislocation structure of fcc metals with medium to high stacking fault energy during uniaxial tension[54], (b) orientation dependence of dislocation structure in bcc metals[58], (c) orientation dependence of deformation twins in fcc metals, black dots indicate orientations that can produce deformation twins (unpublished results from our group, 316L stainless steel was used in this study), (d) orientation dependence of dislocation structure during fatigue loading of fcc metals[59], (e) types of dislocation structure with different orientations, types 1, 2, and 3 corresponding to I, II, and III in (a) and (b), respectively
