Aging Property of Cu-Ag-Zr Alloy

摘要：

Cu-Ag-Zr alloy was produced 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 systematically at different aging temperatures and times under different cold deformation. It has been observed that the Cu-Ag-Zr alloy has an excellent combination of microhardness and electrical conductivity aging at 450℃ for 4h, the microhardness and the electrical conductivity reach 126HV and 84.4％IACS, respectively. The cold deformation prior to aging can accelerate the precipication of the second phase, and imprive the properties of the the Cu-Ag-Zr alloy. Aging at 450℃ for 0.5h after 80％ cold deformation, the microhardness and the electrical conductivity of the Cu-Ag-Zr alloy can reach 134HV and 84.6％IACS, respectively.
