摘 要：Al2O3 dispersion-strengthened copper alloy was prepared by reactive synthesis and spark plasma sintering（SPS） process. Studies show that nano-sized c-Al2O3 particles with 27.4 nm mean size and 50-nm interval are homogeneously distributed in copper matrix. The density of SPS alloy is about 99 %, meanwhile, the electrical conductivity of sintered alloy is 72 % IACS and the Rockwell hardness can reach to HRB 91.
