Impact of In element on the melting point and properties of Pb-56Bi-In eutectic alloy.

Based on advanced first-principle calculations driven by density functional theory, our study used fusion casting techniques to incorporate minute quantities of In into the conventional Pb-56Bi eutectic alloy. Detailed examination identified the critical parameters of the prepared materials, including melting point, phase formation and microstructure. The initial Pb56Bi alloy had a melting point of 125°C, while the inclusion of In yielded Pb-56Bi-XIn (X represents the percentage of In element) and decreased the melting temperature to 85.7°C–119.7°C.
