在合金熔体中添加界面活性元素有利于形成弥散良好的难混溶合金微观结构。一个简单但有效的标准 $- L_{乙 - A} < （ L_{A - 我} - L_{乙 - 我} ） < L_{A - 乙}$ 建议选择A（溶剂）-B（溶质）不混溶合金的界面活性元素i ，其中L _A-B、LB _-A、L _A-_i和L _B-_i是液体 AB 合金的相互作用能参数分别为富A角、富B角中的液态AB合金、富A角中的液态A- i合金和富B角中的液态B - i合金。对不同元素微合金化的Al-Bi和Zn-Pb合金进行了凝固实验。通过将其预测与实验结果进行比较来验证所提出的标准。

A simple criterion for the selection of interfacial active element to control liquid-liquid decomposition of immiscible alloys

Adding an interfacial active element to alloy melt is beneficial to the formation of a well-dispersed microstructure of immiscible alloys. A simple but effective criterion $- L_{B - A} < (L_{A - i} - L_{B - i}) < L_{A - B}$ is proposed to choose the interfacial active element i for an A (solvent)-B (solute) immiscible alloy with L_A-B, L_B-A, L_A-_i and L_B-_i being the interaction energy parameters for the liquid A-B alloy in the A-rich corner, the liquid A-B alloy in the B-rich corner, the liquid A-i alloy in the A-rich corner and the liquid B-i alloys in the B-rich corner, respectively. Solidification experiments were conducted on Al-Bi and Zn-Pb alloys micro-alloyed with different elements. The proposed criterion is verified by comparing its predictions with the experimental results.
