Abstract: The shape of the kink is studied when intense plastic deformation is applied by torsion. It is shown that the process of transition to a stationary state in a two-component copper solution is oscillatory. The behavior of the rates of change in the densities of edge and screw dislocations as functions of deformation is revealed, which leads to a spiral dependence of these dependencies.

Keywords: kink, dislocations, order parameter, phenomenological landau theory, lifshitz invariants, intense plastic deformation by torsion, self-similar substitution.
