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.

高能外载荷作用下Guinier-Preston区对非弹性过程的影响特征

本文对时效二元合金中边缘位错系在高能外力冲击下的运动进行了理论分析。在缺陷动态相互作用理论的框架下，得到了动态屈服强度与位错密度关系的解析表达式。结果表明，在时效的二元合金中，高浓度的Guinier-Preston带导致了最小依赖的出现。
