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Ti Al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。
The influence of interstitial elements on the valence electron structure of TiAl alloy was calculated by the average unit cell and average atomic model of solid and molecule empirical electron theory. At the same time, the melting point and allotrope of the interstitial element were calculated according to the bond energy formula Change the temperature change. Gap elements increase the atomic heterogeneity of alloying elements, causing serious anisotropy of the bond structure, resulting in a decrease in melting point.
