| Abstract: | Al 2O 3/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 Al 2O 3 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 Al 2O 3 particulate in aluminium liquid can be solved effectively by alternative processing parameters. The composites possess relative toughness and good wear resistance. |
