Abstract:A Cu-Cr-Zr-Mg alloy was prepared with spray forming technology. The microstructure was observed and the microhardness, tensile strength and electrical conductivity of alloy after thermal mechanical processing were tested at ambient temperature. The results show that the good combination of high strength and high electrical conductivity can be achieved via spray forming and subsequent thermal mechanical treatments.
Key words: spray forming; thermomechanical treatment; Cu-Cr-Zr-Mg alloy; property
