摘要
这项研究的最终目标是找到一种方法，用一种无毒的替代品取代有毒的铅基焊料，同时保留传统焊料的所有理想特性。在这项工作中，利用滴入式量热计测量了锡-镓-铟三元合金体系在 673 K、723 K 和 773 K 不同温度下沿六个横截面的整体混合焓和部分混合焓。将纯锡块滴入熔融的 Ga0.25In0.75、Ga0.50In0.50、Ga0.75In0.25 合金中，并将纯铟块滴入 Ga0.25Sn0.75、Ga0.50Sn0.50、Ga0.75Sn0.25 中。为了计算相互作用参数，使用了考虑置换溶解机制的 Redlich-Kister-Muggianu (RKM) 模型。Kohler、Muggianu、Chou、Toop 和 Hillert 等几何模型被用来确定积分混合焓，并与实验数据进行比较。结果表明，理论模型与研究结果之间存在良好的一致性。
Measurements of Enthalpies of Mixing of Sn–Ga–In Ternary Alloy System by Calorimetric Technique
The ultimate objective of this study is to find a way to replace toxic lead-based solder with a non-toxic replacement that retains all of the desirable characteristics of the conventional solder. In this work, the integral and partial enthalpy of mixing for Sn–Ga–In ternary alloy systems were measured by the help of drop calorimeter along six of the cross sections at different temperatures of 673 K, 723 K and 773 K. Pieces of pure tin were dropped into molten Ga0.25In0.75, Ga0.50In0.50, Ga0.75In0.25 alloys and pieces of pure Indium into Ga0.25Sn0.75, Ga0.50Sn0.50, Ga0.75Sn0.25. In order to calculate the interaction parameter, Redlich–Kister–Muggianu (RKM) model was used which considers the substitutional solution mechanism. Geometric models i.e. Kohler, Muggianu, Chou, Toop, and Hillert have been used to determine the integral mixing enthalpies and compared with experimental data. It has been seen a good agreement between the theoretical models and results of this study.
期刊介绍：
Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
