Under the assumption of structural softening of plastic deformation in metals, a
solution of the system of equations for the ensemble of dislocations is obtained describing a
running front for the dislocation density (soliton). Such dislocation charge is able to destroy
deformation barriers and cause an athermal mechanism of the instability of the lowtemperature plastic deformation.
Keywords: low-temperature deformation, kinetic instability, dynamic pile-up of dislocations |
