FEATURES OF THE INFLUENCE OF GUINIER-PRESTON ZONES ON INELASTIC PROCESSES UNDER HIGH-ENERGY EXTERNAL LOADS

A theoretical analysis of the motion of an ensemble of edge dislocations in an aged binary alloy under conditions of high-energy external influences 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 a minimum on the resulting dependence.
