Effects of High Pressure and Aging Treatment on Electrical Conductivity of Cu-Cr Alloy

DUAN Wen-yan(Department of Electromechanical Engineering,Qinhuangdao Vocational Technological College,Qinhuangdao 066100,China)  
Effects of high pressure and aging treatments on electrical conductivity of Cu-Cr alloy were studied.The results show that high pressure treatment could decrease electrical conductivity of the Cu-Cr alloy,however,high pressure treatment followed by optimum aging treatment could increase the electrical conductivity and remarkably shorten aging time to reach higher electrical conductivity.The higher electrical conductivity,18.76 MS·m-1,could be obtained after the alloy was treated with 3 GPa pressure and followed by aging at 500 ℃ for 2 h.
