Abstract:Thermal-mechanical treatment is critical for the synthesis of Cu-Ni-Si alloys with high strength and conductivity. In this work, a high-temperature/short-time pre-aging treatment (600 °C, 10 min) was introduced to the thermomechanical processes of Cu-Ni-Si alloys, and the effects of pre-aging on the microstructure and properties of the alloy were investigated in detail. The results showed that Ni2Si particles precipitated from the matrix during pre-aging, promoting the formation of a nanoscale microstructure after cold rolling (cold rolled by 85% reduction).
