我们报道了熔体流动引起的对流输运对单组分(纯)和双组分(合金)熔体中枝晶生长的比较影响。我们使用了一个在对流输运影响下的快速和缓慢枝晶生长的尖锐界面模型进行了分析。作为例子，分别研究了钛熔体和二元TiAl熔体的凝固过程。在标度分析的框架下，讨论了熔体对流输运对单组分枝晶和二元枝晶生长影响的主要差异。由AIP出版公司出版。
We report on the comparative influence of convective transport due to flow in the melt on dendrites growing in one-component (pure) and two-component (alloy) melts. We perform an analysis using a sharp interface model of slow and rapid dendritic growth under the influence of convective transport. As examples, solidification of melts of Ti and binary TiAl, respectively, is investigated. The observed principal differences in the effect of convective transport in melt on the growth of one-component and binary dendrites are discussed in the frame of a scaling analysis.
