摘要
Sn-Bi alloys form some of the common types of Pb-free solders. Au is used as one of the under bump metallization layers due to advantages such as corrosion resistance and anti-oxidation properties. Phase equilibria information plays a vital role in the development of materials technology and serves as an important tool to understand interfacial reactions at heterointerfaces. In this study, the phase equilibria in the Au-Bi-Sn ternary system were experimentally investigated at temperatures of 80, 125, and 150 degrees C. The results indicated that a ternary phase with a composition of Au45-48-Bi36-38-Sn14-19 (at.%) was found in the Au-Bi-Sn ternary system at these three temperatures.
