The activities and free energies of formation of solid Ni-Pt alloys at 1625ยฐK were calculated from vapor-pressure measurements obtained with a torsion-effusion apparatus. Heats of formation at 298ยฐK were determined by liquid-tin solution calorimetry. The entropies of formation at 1625ยฐK were compu

The relative thermodynamic properties of the Al-Ag system have been determined in the temperature range 642-820ยฐK by means of emf measurements and compared with the local atomic arrangements determined from diffuse X-ray scattering. Qualitative agreement is obtained with both the quasichemical and
The relative thermodynamic properties of solid iron-aluminum alloys were obtained in the vicinity of 900ยฐC by e.m.f. measurements, using a molten chloride electrolyte. The heats of mixing are large and negative, with HM = -8200 Cal/g atom at 50 at.?& Large negative entropies of mixing were also obs
