研究了Mg-0.6Si-xZn（x=0 ~ 1. 6wt%）合金的显微组织和力学性能，揭示了Zn对共晶Mg 2Si形貌的变质作用。结果表明：0.5- 1.3wt%Zn有效地改变了Mg_2Si共晶组织的形貌，使其由层状结构变为细小纤维状，从而显著提高了Mg-Si合金的力学性能。Zn含量的进一步增加使Mg_2Si由细纤维状变为汉字状。建议Mg-Si-Zn合金中Zn含量不应超过1.5wt%，以获得良好的力学性能。
Microstructure and mechanical properties of Mg–0.6Si–xZn alloys (x=0–1.6wt%) were investigated to reveal the modification effect of Zn on the morphology of eutectic Mg2Si. It was found 0.5–1.3wt% Zn effectively modified the morphology of eutectic Mg2Si from laminated structure to fine fiber, and in turn improved significantly the mechanical properties of Mg–Si alloy. Further increase in Zn content changed Mg2Si from fine fiber to Chinese script shape. It was suggested that the Zn content should not exceed 1.5wt% in Mg–Si–Zn alloy in order to get good mechanical properties.
