| 摘 要： | 研究了Ce对Al—16％Si合金熔体粘滞性的影响。结果表明：Ce的加入增加了合金熔体的粘度，且随着Ce含量的增加粘度值也增加。结合加入Ce的Al—16％Si合金氢含量的变化、凝固组织和DSC曲线研究了熔体结构的变化，分析了粘度与液态结构变化之间的关系。

| Abstract: | Viscosity of Al 16% Si alloys modified by Ce adding with different contents was studied. The results showed that the viscosity increased with the addition of Ce and their content. The variation of liquid structure and the relations between the liquid structure and the viscosity were discussed and analyzed for Al 16% Si alloys according to the variation of the hydrogen content, the solidification structure and the DSC curves. |

| Keywords: | viscosity hydrogen content liquid structure Al-16% Si alloy |
