Abstract
Flory's expression for the free energy of mixing of binary liquid alloys with atomic size mismatch is modified by introducing the concentration dependency of the heat of mixing given by the semiempirical theory of Miedema. The resulting expression is used to study the concentration fluctuations in liquid Na K and Na Cs alloys.
Résumé
L'expression de Flory pour l'énergie libre de mélange dans les alliages liquides binaires constitués d'atomes de dimensions différentes est modifiée par l'introduction de la dépendance en concentration de la chaleur de mélange, donnée par la théorie semi- empirique de Miedema. L'expression résultante est utilisée pour étudier les fluctuations de concentration des alliages liquides Na K et Na Cs.
