将铝硅过共晶合金凝固过程中析出的初生硅颗粒视为夹杂物颗粒。
The primary silicon particles precipitating from the solidification of Al-Si hypereutectic alloy was regarded as inclusions.
随着熔体过热温度的升高， 凝固组织中初生硅形状由多边形向星形及树枝状转变。
At higher overheating temperature, the shape of primary silicon becomes the star-shape and tree-shape.
采用旋转磁场，研究了密度比周围铝熔体密度大的初生硅夹杂物颗粒在旋转磁场下的分布规律。
An experimental apparatus applied with RMF was employed to study the distribution of silicon particle with density larger than its surrounding molten aluminum alloy under magnetic field.
