Abstract
A technique has been proposed for determining thermodynamic activities in a binary alloy from measurements of the pressure of hydrogen gas equilibrated with the alloy and the hydride of one of the components. The technique is similar to a method by equilibration of oxygen gas with an alloy and the oxide of a component. With the use of this technique, activities of the components in the Ti-Cu system at 773 have been measured. From the measured activities, the standard free energies, enthalpies, and entropies of formation for intermetallic compounds “TiCu4”, “TiCu”, and “Ti2Cu” have been determined.
