摘要
应用固体与分子经验电子理论，对ＮｉＴｉ合金的母相和马氏体相进行了价电子结构分析，计算了合金在两种状态下的结合能。计算结果与实验相符很好；在此基础上对ＮｉＴｉ合金的马氏体相变前后的宏观杨氏模量的变化从电子结构角度进行了解释。
y using Empirical Electronic Theory in Solid and Molecules, valence electron structure and theoretical cohesive energy for parent phase and martensite phase of NiTi alloys have been made, which agree well with to the experimental data. With the results, the changes of macroscopic Yound′s modules on martensite transformation have been discussed in the view of electronic structure.
