中间合金中的Nb基金属间化合物是初生Al枝晶形核的有效异质形核基质。在LM25合金中加入96Al-2Nb-2B中间合金可以显著细化其组织特征，并在很大的冷却速度范围内实现细化。防止了慢速冷却条件下柱状晶的形成。(C)2015年提交人。Elsevier B.V.出版。这是一篇基于CC by License(http://creativecommons.org/licensesiby/4.0/).的开放获取文章
Nb-based intermetallics contained in the master alloy act as potent heterogeneous nucleation substrate for the nucleation of primary Al dendrites. The addition of the 96Al-2Nb-2B master alloy to the LM25 alloy permits to significantly refine its microstructural features and the refinement is achieved in a great range of cooling rates. The formation of columnar grains at slow cooling rates is prevented. (C) 2015 The Authors. Published by Elsevier B.V.
