【Abstract】 Existing processes for producing copper alloys with high strength and high electrical conductivity are reviewed and compared with that for producing in situ composites based on directional solidification. The in situ composites utilize fully the high electrical conductivity of copper base and strengthening effect of second phase and avoid some problems such as wetting and chemical reaction on phase interface. It therefore has wide application prospects for producing high strength and high electrical conductivity copper materials.更多还原
