| 1 | CALCULATION OF THE VACANCY VOLUME OF METALS BY MODIFIED BROOKS' MODEL显示文摘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. | W.H.Qi M.P.Wang W.Y.Hu B.W.Zhang | 2004 | Acta Metallurgica Sinica(English Letters)2004，17，6： | 0 |
