Magnesium has applications in the automotive and aerospace industries that can significantly contribute to greater fuel economy and environmental conservation. The Mg alloys used in the automotive industry could reduce mass by up to 70 pct, providing energy savings. However, alongside the advantages there are limitations and technological barriers to use Mg alloys. One of the advantages concerns phenomena occurring at the interface when joining materials investigated in this study, in regard to the effect of temperature and soldering time for pure Mg joints. Eutectic Zn-Al and Zn-Al alloys with 0.05 (wt pct) Li and 0.2 (wt pct) Na were used in the soldering process. The process was performed for 3, 5, and 8 minutes of contact, at temperatures of 425 °C, 450 °C, 475 °C, and 500 °C. Selected, solidified solder-substrate couples were cross-sectioned, and their interfacial microstructures were investigated by scanning electron microscopy. The experiment was designed to demonstrate the effect of time, temperature, and the addition of Li and Na on the kinetics of the dissolving Mg substrate. The addition of Li and Na to eutectic Zn-Al caused to improve mechanical properties. Higher temperatures led to reduced joint strength, which is caused by increased interfacial reaction.

镁在汽车和航空航天工业中的应用可以极大地提高燃油经济性和环境保护。汽车工业中使用的镁合金可将重量减少多达70％，从而节省了能源。然而，除了优点之外，使用镁合金还有局限性和技术障碍。关于温度和纯Mg接头的焊接时间的影响，优点之一涉及在本研究中研究的连接材料时在界面处发生的现象。在焊接过程中使用了Li（共重量百分​​比）Li和Li（共重量百分​​比）0.2（wt pct）的共晶Zn-Al和Zn-Al合金。该过程在425°C，450°C，475°C和500°C的温度下进行了3、5和8分钟的接触。对选定的固化焊料-基板对进行剖切，通过扫描电镜观察了它们的界面微观结构。设计该实验是为了证明时间，温度以及Li和Na的添加对溶解Mg底物动力学的影响。向共晶的Zn-Al中添加Li和Na导致改善了机械性能。较高的温度导致界面强度降低，这是由于界面反应增加所致。
