摘要
采用特征晶体模型计算了Ｎｉ３Ａｌ合金中的Ｎｉ和Ａｌ原子的半径。依据特征晶体模型理论和从硬球模型所得到的不同间隙的间隙半径方程，计算了不同间隙的间隙半径、间隙能和固溶度。计算结果表明：硼原子趋向于占据６个Ｎｉ原子所围成的间隙。
The radii of Ni and Al atoms in Ni 3Al alloy have been calculated by using the characteristic crystal model. On the base of the characteristic crystal model theory and interstitial radii equations of different interstices that induced from hard sphere model, the interstitial radii, interstitial energy and solutions of different interstices have been calculated. The results showed that boron atom trends to occupy the interstices surrounded by 6 Ni atoms.
