| Abstract: | The CuCrZr matrix composite reinforced by VC ceramic particle was fabricated by melting-casting, and the influences of the heat treatment parameters on microstructure and properties of the material were discussed. The results show that the copper matrix strengthened by paucity element of Cr and Zr after appropriate aging treatment process can obviously improve the mechanical property and gives play to the synchronal enhancement of dispersion strengthening and compound strengthening. |
