The results reveal that with increasing the Si content, the fluidity of Mg-Si alloy is decreased, resulting in the increase of in-situ Mg2Si particles in the composites and the generation of more developed dendrite, such as Chinese script.

• 试验结果表明,随着合金中Si含量的增加,合金的流动性降低,复合材料中原位Mg2Si的数量增多,树枝晶形态更为发达;
