1.IntroductionVacancies are very important point defects, which have remarkable influence on the mechanical, optical, and electrical properties of materials[1]. Besides the vacancy formation energy, the vacancy volume is also an important quantity to understand of many processes in metals. The vacancy volume can be measured by experiments[2-5] or calculated by theories[6-13]. Due to different experimental methods, the experimental values are different from each other, for example, the exper… 相似文献

To modify the shape difference between the spherical vacancy and the realistic vacancy, a shape factor is introduced into Brooks’ vacancy model. It is shown that the modified model is more efficient in predicting the vacancy volume of metals than the original one, and the calculated vacancy volumes of 17 metals by the modified model agree with the values reported in literatures. Furthermore, the present results show that the vacancy shape may contribute 2%-9% to the whole vacancy volume. 相似文献
