摘要：

A thermodynamic analysis of the binary Gd-Mg system is presented, and its description is optimized using the experimental phase diagram and thermodynamic values. The excess Gibbs energies of the liquid and solid (alpha-Gd, beta-Gd and Mg) solutions were described according to the Redlich-Kister polynomial expansion. The intermediate compounds (GdMg, GdMg2, GdMg3 and GdMg5) were assumed to be stoichiometric phases. A good agreement between the experimental and the computed phase diagram is shown. The results are briefly discussed and compared with those for other binary rare earth-Mg alloys.
