Abstract: The motion of dislocations during low-temperature deformation of two-component alloys has been studied. The condition is found under which the appearance of a region with negative slope of strain-rate dependence of the yield stress is possible that leads to the onset of dynamic instability and jumpwise straining. An analytic expression for the critical magnetic field capable of suppressing these jumps is obtained.

Keywords: dislocation, magnetic field, serrated deformation.
