Abstract
The high strain rate deformation of metals and alloys, containing alloying elements is theoretically analyzed. An expression for the contribution of alloying elements to deforming stresses is obtained. Solid solution hardening of alloys increases linearly with increasing plastic deformation rate. The concentration dependence of the mechanical properties under high-strain-rate deformation differs essentially from the analogous dependence under quasi-static deformation. This difference is due to the action of collective dynamic effects. The concentration dependence of hardening under high-strain-rate deformation is determined by the competition between the interaction of the dislocation with alloying elements and dislocations of the ensemble. If interaction with alloying elements dominates, hardening increases in proportion to the square root of the concentration. If the collective interaction of dislocations predominates, the hardening increases linearly with increasing concentration.
