Article Preview

Mg2Si particle reinforced in-situ Al-Si composite is prepared by melt superheating, and the microstructure and properties of the composite are researched. The results indicate that it is feasible that the melt superheating is applied to preparing Mg2Si particle reinforced in-situ Al-Si composite, and the suitable preparing parameters of melt superheating on the alloy are obtained. When the superheating temperature is 860°C and holding time is 25 min, the average size of Mg2Si particle in the alloy will be reduced to 11μm compared with 34μm without melt superheating, and the mechanical properties of the composite is obviously improved.
