Аннотация

The aim of this work is to evaluate the influence of the crystallographic orientation and crystal's symmetry on the ability to self-organize under a compression deformation at various scale levels. Nickel single crystals with the [111] contraction axis and {110}, {112} lateral faces were investigated. Single crystals in the shape of rectangular and triangular prisms were used in this work. Different geometric shapes of the crystals made it possible to establish the influence of the symmetry crystal on the plastic deformation processes. The methods of fractal analysis were used to assess the self-organization level. It is established that the processes of self-consistency of deformation at the microlevel are realized due to the self-organization of the dislocation structure, at the mesolevel due to a correlated shear in parallel slip planes. It is shown that the coincidence of the sample symmetry with the crystallographic symmetry of the compression axis promotes an increase in the degree of the crystal deformation self-consistency at all scale levels.
