| Abstract: | Cu-Ag-Zr alloy was prepared by means of a vacuum induction melting.By means of the analysis of microhardness,electrical conductivity,and transmission electron microscopy,the aging property of the Cu-Ag-Zr alloy was investigated at different aging temperatures and time under different cold deformation.It is observed that the Cu-Ag-Zr alloy has an excellent combination of microhardness and electrical conductivity aged at 450 ℃ for 4h,the microhardness and the electrical conductivity reach 126 HV and 84.4% IACS,respectively.Cold deformation prior to aging can accelerate the precipication of the second phase,and improve the properties of the Cu-Ag-Zr alloy.Aging at 450 ℃ for 0.5 h after 80% cold deformation,microhardness and electrical conductivity of the Cu-Ag-Zr alloy can reach 134 HV and 84.6% IACS,respectively. |
