We model the elastic field near the void using a new Molecular Static method. Results show that the atom displacements near nanovoids significantly differ for various crystallographic directions in bcc metals. Using some results of these calculations, we estimate the void growth rates following various directions basing on recently obtained equations of vacancy diffusion under strain. This growth rate anisotropy helps to explain the change in shape observed for many voids.

孔隙附近原子结构的模拟及其生长速率各向异性的估计

我们使用新的分子静态方法对孔隙附近的弹性场进行建模。结果表明，在密件抄送金属中，纳米空隙附近的原子位移对于不同的晶体学方向都存在显着差异。使用这些计算的一些结果，我们基于最近获得的应变下空位扩散方程，估算了沿着各个方向的空隙增长率。该生长速率各向异性有助于解释在许多空隙中观察到的形状变化。
