Abstract: Bi–Sn alloy phase diagram under pressure was re-calculated using the CALculation of PHAse Diagrams method by applying new density data. Theoretically, alloy phase diagram under pressure can be calculated with bulk thermodynamic database and thermophysical property data such as density and sonic velocity. In the recent study by Emuna et al. (J Alloys Compd 687:360–369, 2016), thermodynamic parameters were determined from literature values with additional modification to fit experimental data of phase boundaries. In this study, density of liquid Bi–Sn alloys was re-evaluated with an advanced density measurement technique: the constrained drop method. By applying the new density data, the Bi–Sn phase diagram under pressure could be calculated successfully without any modification of thermodynamic parameters.
