| 摘 要： | 根据固体与分子经验电子理论，对ＴｉＣ１－ｘＮｘ固溶体的价电子结构进行分析，结果表明：固溶体中最强键上的共价电子数ｎＡ随ｘ增加而减少，硬度随ｘ的增加而降低的实质是ｎＡ的减少。并从电子结构层次上证实在ＴｉＮ中以Ｃ原子取代部分Ｎ原子可以提高其稳定性。

| Abstract: | The valence electron structure of TiC 1-x N x solid solution is analyzed according to solid and molecule empirical theory.The result shows that the covalence electron number n A in the strongest bond and the hardness in solid solution decrease with the increase of x due to the decrease of n A. It is verified in electron structure level that the stability can be enhanced when partial nitrogen atoms are replaced by carbon atoms in TiN. |
