Effects of Cr addition on the microstructural, mechanical and electrical characteristics of Cu-6Â wt.%Ag microcomposite

Cu-6 wt.%Ag and Cu-6 wt.%Ag-1 wt.%Cr microcomposites were prepared by heavy drawing. The morphology of filamentary bundles was observed and the tensile strength and electrical conductivity determined. The effect of Cr addition was discussed according to the changes in the microstructure, strength and conductivity with various draw ratios for both alloys.
