The aim of work — to determine the influence of conducting electrons and interphase bondaries of normal and superconducting phases in the mixed state type — II superconductor on the strengthening and deforming stress changes under the loading in normal, superconducting or mixed states or during their changes in connection on influence of residual magnetic flow and also studying the regularities of plastic flow instabilities during deformation in normal or superconducting states. The method of investigation — deformation of metal with constant rate at low temperatures, destruction of residual magnetic flow by electric pulse treatment, the investigation of low temperature jumping deformation. The peculiarities of dislocation drag by conducting electrons and type — II superconductor mixed state magnetic structure have been investigated. The volume concentration of normal phase and magnetic structure characteristics have been determined in accordance to the force of external magnetic field and sample geometry. The increments to deforming stress connected with two channels of energy dissipation have been separated. The influence of mixed state static boundaries on the additional strengthening in longitudinal and transverse magnetic field has been investigated. The character of plastic deformation under conditions of heat instability at the loading in normal and superconducting states has been investigated.
