Abstract

Silver–copper–nickel alloy has been wildly used in the military field as energy transfer component and signal transmission parts for its high conductivity and excellent mechanical properties. Rolling and heat treatments parameters influence the alloy properties effectively. However, systematic study on the parameter influence on the alloy properties and microstructure was seldom conducted. Herein, the influence of deformation, temperature of heat treatments and cooling mode on the alloy properties and microstructure were studied by orthogonal experiments design. The results showed that the order of the effects of processing parameters on the mechanical properties was deformation, annealing temperature, and homogenizing temperature. The hardness was the highest with 155 Vickers hardness, when the alloy was treated with homogenizing treatment temperature of 720 °C, annealing temperature of 250 °C, and cold rolling deformation of 55%. The microstructure observations showed that the alloy presented eutectic structure and distributed along the direction of deformation.
