作者提出了一种有效而准确的计算位错运动晶格摩擦垒的方法。该方法利用位错核结构的原子模型。本文给出了离子晶体MgO和KCl中1/2 α(110)刃位错的晶格摩擦势垒和Peierls应力的计算结果,并与实验进行了比较。
The authors present an efficient and accurate method of calculating the lattice friction barrier to dislocation motion. This method makes use of an atomistic model of the dislocation core structure. Results of calculations for the lattice friction barrier and the Peierls stress of 1/2a(110) edge dislocations in the ionic crystals MgO and KCl are presented and compared with experiment.
