ON THE ELASTIC INTERACTION BETWEEN DISLOCATION LOOP AND LATTICE VACANCY
位错环与点阵空位间的弹性相互作用

In this article, the elastic model of lattice vacancy is critically analysed, and a general expression for the interaction energy of vacancy with an arbitrary internal stress system is given. As an example of physical interest, the formula for the elastic interaction energy of prismatic dislocation loop and vacancy is derived, and numerical results on dislocation loop in Al are presented and discussed.
