Abstract:Al2O3/Al composites were manufactured through melt-stirred composing and die-forging in semi-solid. The effect of processing parameters on the absorbability and dispersiveness of Al2O3 particulate in aluminium liquid was investigated. The strength，impact toughness and wear resistance of the composites were also examined. Results show that the problems of the dispersiveness of Al2O3 particulate in aluminium liquid can be solved effectively by alternative processing parameters. The composites possess relative toughness and good wear resistance.
Key words: aluminium matrix composites; particulate reinforced; melt-stirring composing
