摘要
The copper alloys with high strength and high conductivity are important functional materials with full of potential appliances. Cu-1.2%Cr(mass fraction) alloy was prepared successfully by spray forming. The effects of the thermo-mechanical treatments on the microstructure and mechanical properties of the alloy were studied and the strengthening mechanism was analyzed. The results show that the spray-formed Cu-1.2%Cr alloy has excellent mechanical properties with optimized thermo-mechanical treatments and the main strengthening mechanism is the precipitation of the coherent chromium precipitates, which is resulted from the decomposition of the supersaturated solid solution.
