| Popis: | Strain localization in the region of elastic distortions is revealed in nickel dynamic recrystallization grains during torsion in Bridgman anvils, which leads to the formation of reorientation nanobands with the elastic lattice curvature equal to hundreds of degrees per micron. It is shown that the nanobands are formed by the motion of partial disclination nanodipoles, i.e., zones of constrained elastic shear and rotations distinguished by extremely high local internal stress gradients. |
