Abstract
The Ag-Sn binary system is reoptimized because of the increasing interest in lead-free solder development. The ordered semistoichiometric Ag3Sn phase is described as a line compound while the other phases are represented by Redlich-Kister expressions. Results are compared with previous efforts, and the agreement between the calculated phase diagram and the assessed phase boundary data has been significantly improved while reproduction of experimental data for thermodynamic properties remains excellent.
