A thermodynamic analysis of the undercooled liquid and glass transition in the ternary Cu-Mg-Y system has been carried out. To this purpose, a number of experimental data on the amorphous phase and on the undercooled liquid has been considered (glass transition temperatures, specific heat). A proper modelling of the glass transition has been applied, which has been proved suitable for the description of thermodynamic properties of the liquid-amorphous phase. Calculated and experimental quantities show a good agreement. An improved description of the behaviour of the specific heat of the liquid phase on undercooling has been obtained. The present thermodynamic assessment is suitable for estimating the Glass Forming Ability in this ternary system.
