摘　　要：The in situ synthesized reinforced phases in the matrix have the advantages of uniform dispersion and good interfacial bonding.Aiming at in situ synthesizing reinforced phases in CuW composite,a novel methodology for direct synthetization of CuW composite reinforced with lamellar precipitates by aluminothermic reduction is proposed,and CuW composites and their slags were systematically analyzed.The results indicate that,at temperatures of above 1800 K,the mole percentage of Al,copper oxides,tungsten oxide,and CuO·Al_(2)O_(3)increased rapidly with temperature increasing,which was not conducive to CuO and W0_(3)thermite reduction.
