Effect of Mg2Si Contents on Microstructure of Mg2Si Particle Reinforced Hypereutectic Al-Si Alloy Composites

Abstract:

Article Preview

Mg2Si particle reinforced hypereutectic Al-Si composite was prepared by direct melt reaction, and the effects of Mg2Si content on the microstructure of the composite were researched. The results indicated that the morphology of Mg2Si obviously changed with Mg2Si contents increasing, in which the morphology of Mg2Si in the composite had changed from polygon block to characters like and finally became coarse dendrite. Formation of α-Al grains in the composites with the high Si and Mg content was discussed.
