Abstract
The formation and propagation of localized nanobands with elastic lattice distortion in nickel crystallites have been studied within the molecular dynamics framework. Such nanobands are formed due to the presence of regions with tensile and compressive stresses on the free surface. The nanoband propagation region is characterized by a collective vortex motion of atoms. The effect of different-type grain boundaries on nanoband propagation was investigated. It was shown that grain boundaries do not significantly affect the reorientation angle in the nanoband, but the nanoband propagation direction changes after crossing a grain boundary in accordance with the different crystallographic orientation of grains.
