摘要
基于固体与分子经验电子理论(EET),对纯金属晶体Cu、Cr以及Cu-Cr合金固溶体进行价电子结构分析,从相空间价电子结构角度探讨合金元素的合金化行为。纯金属晶体的计算结果表明:Cu处于第9杂阶,Cr处于第7杂阶;合金元素Cr的溶入,能够提高纯铜晶胞的原子键引力,强化铜基体,从电子结构层次分析合金元素Cr对基体产生的固溶强化作用。
Based on the empirical electron theory in solids and molecules (EET), the valence electron structure of the phase in copper, chromium, and Cu-Cr alloy were calculated, and the alloying behavior of alloy element was explored by the valence electron structures of phase. The results show that copper is on the ninth hybrid level, and chromium is on the seventh hybrid level in the pure metal crystal. The addition of chromium can enhance the atomic binding forces and strengthen the alloy matrix. The solid solution strengthening of chromium was analyzed from the level of electron structure.
