Complex Modification on Microstructure and Properties in Mg₂Si Reinforced Hypereutectic Al-Si Composite

Abstract:

The effects of complex modification which mainly consisted of mixed rare earth oxides and CaCO₃ on microstructure and properties in Mg₂Si reinforced hypereutectic A1-Si composite were researched. The results indicated that the morphology of Mg₂Si particle changed from irregular or crosses to polygonal shape, and its size obviously decreased. The hardness and wear resistance of the composite were improved by the complex modification.
