摘要
通过测量不同含Ｃｅ、Ｌａ量的Ａｌ－Ｓｉ共晶合金熔体的密度、粘度和电阻率，考察了熔体的物性变化与凝固组织之间的相互关系。结果表明，物性变化的转折点与共晶Ｓｉ形貌的改变具有对应的关系。
By measuring the density, viscosity and resistance of Al-Si eutectic melt which contains variant amount of Ce and La elements,the relationship between the physical properties and the solidified structure has been investigated.The results show that the turning points of the changes of physical properties of melt have corresponding relationship with the morphology of eutectic Si.
