WebFurther deformation causes grain sizes to decrease to <0.5 μm, with observable kinking in the crystal lattices (defined here as initially undistorted grains folded about a distinct axis in an angular manner). Kinking of the crystal lattices is often associated with the development of porosity in the hinges of these kinks (Figure 3c). WebThis paper reviewed the research progress of studies on the crystal rotation of single crystals that were deformed by tension and shear and the influences of crystal rotation and dislocation evolution on strain hardening behavior in crystals that were deformed with different initial orientations. The crystal rotation is entirely different depending on …
