Evolution of deformation in nickel single crystals with the compression axis orientation [001] and lateral faces {110}

Abstract

The investigation of Ni single crystals with the compression axis orientation [001] and lateral faces {110} have shown that plastic-deformation at room temperature on the macrolevel occurs by the formation of shear domains and deformation macrobands. The deformation macrobands are formed along the boundary between regions with different stress state conditions. Shear accommodation in neighboring strain domains takes place in the macrobands. It has been established that within a band substructures with misorienlations are formed more rapidly as compared to the surrounding material. The morphology of shear domains on the macrolevel is analyzed. It is demonstrated that in the direction of the macroshear vector of the strain domain the single crystal faces undergo maximum deformation.
