Solute Distribution Factor for Rapid Solidification in Laser Surface Alloying
-
摘要: 本文在充分考慮激光表面合金化過程高溫度梯度產生的Soret效應和液相金屬強制性對流的作用,在Aziz模型基礎之上,從理論上分析了激光表面合金化非平衡凝固過程溶質在界面的分布,并推導出新的溶質分配系數公式。Abstract: 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.
