| 摘 要： | 应用固体与分子经验电子理论的平均晶胞和平均原子模型分析计算了间隙元素对ＴｉＡｌ合金价电子结构的影响，同时根据该理论的键能公式计算了间隙元素影响下的熔点及同素异型转变温度变化。间隙元素提高了合金元素的原子杂价，引起键结构各向异性严重，导致熔点降低。

| Abstract: | Using the average crystal cell and atom models of the empirical electron theory of solids and molecules (EET),the effects of interstitial impurities on valence electron structures and melting point of Ti Al alloys were analyzed.Because of the effects of interstitial impurities,atoms hybridization states increase,bond structures are seriously anisotropic,and the melting points are decreased. |
