Thermodynamic Study of Liquid Mg-In-Sn Alloys

Liquid Mg-In-Sn alloys were studied by the emf method using concentration cells with liquid electrolyte. Experiments were performed for 30 alloys along three sections on the Gibbs triangle with constantt = 0.25, 0.50, 0.75 t = X_Sn/(X_Sn + X_In)] and for magnesium concentration from 0.1 to 0.65 at temperatures from 950 to 1100 K. From the change of the slope of the emf versusT, points on the liquidus surface for sixteen alloys were detected. Calculated partial excess Gibbs energies δG_exMg and partial enthalpies δH_Mg were compared with the results of previous work.
