Thermodynamic Properties of Melts of Ni-Sc(Y, La, Ti) Binary Systems

摘要

The thermodynamic properties of melts of binary Ni-Sc(Y, La, Ti) Systems at 187-1910 K are determined by calorimetry. Large negative values of the heats of mixing are obtained for these Systems. The thermodynamic activities of the components of such melts are calculated from data on the coordinates of the liquidus line. The activities of the melt components of these systems are characterized by large negative deviations from Raoult's law over the whole composition range.
