| Abstract: | In this article,the latest developments of high strength and electrical conductivity copper(alloy)- based composites are generalized from two ways:strengthening methods and properties.The various strengthening principles are analyzed respectively,such as precipitation,fine particles,phase transforming,dispersion and second-phase strengthening methods.Different fabrication processes such as liquid-solid compound foundry process,SHS method, half-solid-state solidification method,powder metallurgy process,composite electroforming process are described.Fac- tors influencing the electrical conductivity are also listed such as elements,its contents,phase structures.The develo- ping tendency of the materials is outlined finally. |
