Nd and Y showed more evident effects than Gd and La due to lower temperature of eutectic reaction with aluminum. In order to investigate mechanism of the formation of the intercellular dispersoid which is being in debate and possibility of suppressing the dispersoid, a nucleation kinetic model which including unsteady nucleation and effect of alloy element was established.
Al-Fe-Mo-Si-Zr-Ti合金粉末具有四种凝固组织,初生Al〓〓,α-Al与Al〓共晶,胞晶及显微胞晶,合金元素Mo的加入,显著提高合金粉末凝固前的过冷度,使10~40μm粉末的凝固机制发生了变化,由导热控制型转变成溶质扩散控制型,从而基本上消除了该尺寸范围内粉末凝固组织中共晶成分和初生相,但对大于40μm的粉末,因共晶区富Zr核心的优先形成而使Mo的作用效果不明显。

The current theory and application of Al-Si alloy mainly focus on the study of hypoeutectic and eutectic, therefore we systematically analyzed the modification process of hypereutectic Al-Si alloy based on the methods and results of predecessors. Several factors including the modification temperature, the content of modifier, the available holding time, the times of repeat melting , the casting temperature and the speed for cooling have been studied in order to understand its effects to the composition, function and performances of primary silicon and eutectic silicon.
