Abstract: The effect of nonequilibrium vacancies generated by laser pulses on the motion of dislocations under the conditions of high-speed deformation is studied. An analytical expression is obtained for the contribution of these vacancies to the dynamic yield strength of metals and alloys and it is shown that the dynamic drag of dislocations by nonequilibrium vacancies leads to a significant increase in the yield strength.
