Thermodynamic calculation of phase diagram in the Bi-In-Sb ternary system

Abstract

A thermodynamic description of the Bi-In-Sb ternary system of lead-free solder alloys using the CALPHAD (Calculation of Phase Diagram) method is presented. Phase equilibria information such as vertical sections, liquidus projection and thermochemical quantities were calculated and compared with the experimental data. The calculated and experimental data are in excellent agreement in most cases.
