The thermodynamic description of the Cu-Ti system is revised as current evaluations of it, while giving a reasonable fit to the phase diagram, do not predict the possibility of amorphization. A new free energy curve for the liquid phase is derived accounting for an excess specific heat of mixing. This latter quantity has been obtained for a few compositions from the difference between the heat of fusion and the heat of crystallization of melt spun ribbons. An increase in stability of the liquid phase on decreasing temperature is shown. Tg and T0 curves for Cu-Ti are calculated and the glass forming range is discussed.
