The formation and evolution of localized nonequilibrium states in nickel crystallite under a complex scheme of mechanical loading is studied in the framework of the molecular dynamics method. Local compressive and tensile loads were applied to the simulated specimens. It was revealed that nanobands of elastic deformation localization are generated and propagated in the specimens. The crystal lattice within nanobands was elastically curved. The influence of mechanical loading on the nanoband structure was studied. Estimates of elastic curvature of the crystal lattice for the formed localized nonequilibrium structural states were obtained. Thermal and mechanical stability of nanobands was investigated. The simulation results were compared with the available experimental data.
