A356铝合金的固化过程. 2.3 分析与讨论 将Al-5Ti-B中间合金加入到A356合金熔体中,大部分的TiAl3相将会溶入熔体中,高温稳定的TiB2相不能直接成为α(Al)初晶的有效形核点,需要在其表面覆盖一层TiAl3/Ti(Al1-xSix)3膜后才与α(Al)有良好的晶格匹配,从而成为初晶有效形核位置[13].溶入熔体 图2 试样4富含稀土相的SEM像... aluminum alloy samples 中的溶质Ti具有很高的生长限制因子(Growth restriction factor, Q),促进了熔体中成分过冷,因此,容易达到初晶形核所需过冷度要求,从而降低初晶晶胞尺寸[14].最近研究[15]指出,Al-7Si合金中添加Al-Ti-B细化剂大大降低了初晶形核所需的过冷度,从而导致柱状枝晶向等轴晶的转变.TiB2相密度较高,在熔体静置时可能......

Regarding the mechanical performances, tensile properties... to play important roles in grain refinement. One is the nucleant particles existing in grain refiners, e.g., Al3Ti [9], TiB2 [10], AlB2 [2] and TiC [11], inducing the heterogeneous nucleation process......
