| Abstract: | Al 2O 3(p)/Al composites was successfully fabricated by casting of the molten Al which is prepared from the reaction between liquid Al and solid CuO particles added into molten Al by stirring.The test results showed that Al 2O 3 could be created by In situ reaction of a comparatively long period between liquid Al and CuO particles. The Al 2O 3 particles created were distributed homogeneously in the Al matrix and resulted in a strongly strengthening effect, and the hardness of the composites was much higher than that of matrix as a result. |
