研究了熔体过热处理对 Mg2Si/Al-Si-Cu 复合材料显微组织的影响。结果表明，随着熔体过热处理温度的升高，初生Mg2Si颗粒形貌由粗大树枝晶转变为等轴晶，尺寸由大于150μm减小至～40μm。共晶Mg2Si相由汉字型转变为块状和/或针状。
The effects of melt superheating treatment on microstructure of Mg2Si/Al–Si–Cu composite is investigated. The results show that, with the increasing of melt superheating treatment temperature, the morphology of the primary Mg2Si particulates change from coarse dendritic to equiaxed, and their size decreases from larger than 150 to ∼40μm. The eutectic Mg2Si phase changed from Chinese script type to massiveness and/or needle like.
