NONIDEAL BEHAVIOR IN LIQUID METAL SOLUTIONS. PART 2 - CHEMICAL-PHYSICAL THEORY MODEL.

The 'physical' model developed previously is coupled with a 'chemical' model to account for the strong negative deviations from Raoult's law in systems forming intermetallic compounds. The resulting chemical-physical model represents well both Gibbs energies and enthalpies of highly solvated metal systems. New data are presented for two titanium systems, for which only a limited composition range is experimentally accessible. The theory permits facile extension of such limited data.
