稳态滑动的晶界进行了讨论，考虑到所施加的应力的势能的变化，当滑动发生扩散住宿。本分析使我们能够在不知道局部应力场的情况下以简单的方式导出各种形状边界处的滑动速率。含第二相粒子的边界的滑动速率也是通过类似的计算得到的。结果与以前的计算由其他研究人员进行了比较，它被发现，由此产生的表达式的滑动率基本上是相同的那些来自更复杂的分析。
Steady-state sliding of grain boundaries is discussed by taking into account the change in the potential energy of an applied stress, when the sliding occurs by diffusional accommodation. The present analysis enables us to derive the sliding rates at boundaries of various shapes in a simple manner without knowing local stress fields. Sliding rate of a boundary containing second phase particles is also derived by similar calculations. The results are compared with previous calculations by other investigators, and it is found that the resultant expressions for the sliding rates are essentially identical to those derived from more complex analyses.
