Crystallographic shear
WebSep 1, 2014 · Therefore, shear banding is preceded by the formation of planar obstacles that are determined by the SFE and by the crystallography of homogeneous dislocation slip. Shear banding, although appearing as a non-crystallographic deformation mechanism, is also associated with large local crystallographic reorientations, i.e. texture changes. WebFeb 26, 2024 · The shears induced by low SF twins can be accommodated by several different deformation systems. In such cases, twin variant selection criteria depending on …
