摘要
本文在充分考虑激光表面合金化过程高温度梯度产生的Soret效应和液相金属强制性对流的作用,在Aziz模型基础之上,从理论上分析了激光表面合金化非平衡凝固过程溶质在界面的分布,并推导出新的溶质分配系数公式。
Considering the influence of the Soret effect and the constrained convection caused by non-uniformity of radial laser energy distribution on solute distribution, the distribution of solute at the interface in non-equilibrium solidification of laser surface alloying is analyzed, and a new formular describing solute distribution factor on the basis of Aziz's model is put forward.
