摘要: Abstract The relative thermodynamic properties of solid aluminum-zinc alloys have been determined over the complete composition range by means a galvanic cell using molten salt electrolyte. results evaluated at 300°C and 380°C indicate that there is substantial positive deviation from ideal behavior. molar heat mixing has maximum value 850 cal/gm atom (heat absorbed) about 60 atomic per cent zinc, entropies are slightly greater than configurational values. For aluminum-rich solutions, partial quantities to aluminum apparently consistent with quasi-chemical theory, but large deviations theory in solutions containing more 40 zinc. Extrapolation data for indicates liquid 440 atom.
