Description

A thermodynamic assessment of the Bi–Sn–Zn ternary system was carried out using the CALPHAD approach along with thermodynamic descriptions from new assessments of the Bi–Sn and Bi–Zn systems. Selected experimental data from the literature and our own work were also used. New sets of optimized thermodynamic parameters were obtained that lead to a very good fit between the calculated and experimental data. The Bi–Sn–Zn system is one of the candidates for lead-free solder materials.
