摘要：

CuO particles were incorporated into pure Al melt to produce Al-Al2O3 in situ particle composites. alpha-Al2O3 and Cu particles were identified in the particles extracted from the composites. Part of the reduced Cu dissolved in the matrix of the composites and increased its microhardness. The hardness and tensile strength of the composites were improved significantly as compared to those of pure Al.
