液相流动在金属凝固中的作用

Roles of Liquid Flow in Metal's Solidification Process

液态金属的流动有多种形式,它对金属冶金、凝固过程有着重要影响。文章从传输过程、凝固组织和成分偏析等三个方面对液相流动的作用作了综述。通过控制液相流动的方式和行为来调节凝固过程的传输行为,达到控制或改善凝固组织和偏析程度的目的。对从事材料冶金和凝固等相关领域的研究人员有较大参考价值。

There are many sorts of flows of melten liquid, it plays an important role in the metal's metallurgy and solidification processes. It was summarized in present paper that the liquid flow acted in the transfers process, solidification structure and componential segregation. Through controlling the mode and the action of liquid flow, the transfers action during solidification could be adjusted in order to improve the solidification structure and componential segregation. It is worth reading for man in relative fields.
