【Abstract】 Cu-0. 62Al₂O₃, powder was prepared by internal-oxidation of Cu-Al powder in this paper. How the difference of the mold pressing-sintering-rolling and isostatic cool pressingsqueezing-rolling technology affected the physical and mechanical properties of Cu-Al₂O₃ composite was studied. The result showed that the technology of isostatic cool pressingsqueezing-rolling was a ideal method to obtain the high compactness. In the mean time, three ways to enhance the compactness of Cu-Al₂O₃ were proposed in this article.更多还原
