摘要：

The effect of crystal orientation of grains on grain growth is investigated by computer simulation. A vertex model which includes the orientation dependence of grain boundary energy is used. It is shown that the orientation effect gives rise to more distortion and more diversity in the shape of the grains. Such a distortion in the shape of grains is measured by the moment tensor, for a quantitative discussion. It is also found that the 1/2-power growth law of the average size of grains still holds under such an anisotropic circumstance.
