Electron theory research on Cu-Cr alloy solid solution

JIA Shu-guo1,2,BIAN Hua-kang1,LIU Ping1,LI Xiang-li1,WU Juan1,ZHENG Mao-sheng3 (1.School of Materials Science and Engineering,Henan University of Science and Technology,Luoyang 471039,China; 2.Henan Key Laboratory of Advanced Non-ferrous Metals, Luoyang 471039,China; 3.Physics Department,Northwest University,Xi’an 710069,China)  
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.
