凝固过程微观偏析数值模拟的研究发展

Development of Investigation on Numerical Simulation of Microsegregation

微观偏析现象对于合金性能和后续加工有非常重要的影响 ,对它的数值模拟研究已受到许多研究者的关注 ;回顾并简单地介绍微观偏析数值模拟的发展 。

Microsegreation phenomenon is very important for alloys due to the fact that the as cast microstructure determines the alloy's mechanical properties and subsequent processing. Researchers have paid much attention on numerical simulation of microsegreation. The paper presents an overview of this field, and points out the limitations of available models. Suggestions for further research are also given in this article.
