研究了添加Al-Ti-B中间合金的纯铝粘度与细化效率的关系。实验结果表明，当凝固样品晶粒尺寸越细时，添加不同Al-Ti-B中间合金后熔体的粘度越高。这表明粘度在一定程度上可以用来近似估计生产中Al-Ti-B精炼剂的精炼效率。本文还通过透射电子显微镜（TEM）分析和差示扫描量热法（DSC）实验对其主要原因进行了探讨。
The relationship between viscosity and refinement efficiency of pure aluminum with the addition of Al–Ti–B master alloy was studied in this paper. The experimental results show that when the grain size of solidified sample is finer the viscosity of the melt is higher after the addition of different Al–Ti–B master alloys. This indicates that viscosity can be used to approximately estimate the refinement efficiency of Al–Ti–B refiners in production to a certain extent. The main reason was also discussed in this paper by using transmission electron microscopy (TEM) analysis and differential scanning calorimetry (DSC) experiment.
