Reoptimization of the Ag–Mg system

Highlights: • The Ag–Mg phase diagram was refined at various temperatures and compositions. • Driving forces were taken into account to determine equilibrium states. • We report a distribution of weighted differences between calculations and experiments. • A good thermodynamic description of the liquid phase needs more high-temperature data. - Abstract: A previous thermodynamic model of the Ag–Mg system built by Lim et al. (1997) was refined by taking into account available literature data on equilibrium states of this system at various temperatures and compositions. The optimization of this system was based exclusively on critically analyzed actual experimental observations retrieved from original publications including recent data on the activity of Mg in the liquid phase at high temperatures
