Abstract

A theoretical analysis of the motion of an ensemble of edge dislocations in an aged binary alloy under conditions of high-energy external impacts has been performed. Within the framework of the theory of dynamic interaction of defects, an analytical expression is obtained for the dependence of the dynamic yield strength on the density of dislocations. It is shown that a high concentration of Guinier–Preston zones in an aged binary alloy leads to the occurrence of a minimum on the obtained dependence.
