| 摘 要： | 采用相场方法模拟了Fe-1.0%C-0.1%Mn三元合金等温凝固过程二维枝晶生长,预测了溶质浓度分布以及Mn元素对枝晶形貌的影响.结果表明:Mn和C浓度分布相似,枝晶主干溶质浓度最低,而在二次枝晶臂之间形成了溶质富集浓度最高.与Fe-1.0%C合金比较,Fe-1.0%C-0.1%Mn合金由于Mn元素的添加抑制了侧向分枝的生长,使二次枝晶不发达.

| Abstract: | The evolution of dendritic growth and solute distribution as well as the effect of Mn element on the dendrite morphology during isothermal solidification for Fe-1.0%C-0.1%Mn ternary alloy are studied by using phase field method. The result of the simulation indicates that the distribution of Mn element is similar to that of C element. The first arm has a low concentration, but the regions between the secondary arms have the highest. The growth of side-branches in Fe-1.0%C-0.1%Mn alloy is restrained as the a... |
