Abstract
The theory of phase boundaries in binary alloys is reviewed in the light of modern work on the nature of the Fermi surfaces in the noble metals. Features of the free-energy-composition curves are investigated in relation to the density of electronic states, and the older interpretation of the Hume-Rothery rules is reexamined. General properties of the Fermi surface in the neighbourhood of the centre of the hexagonal faces of the Brillouin zone in copper, and the nature of the singularity in the density of states function at the point of contact are considered. The way in which the electronic specific heats of copper based alloys can be reconciled with a contacting Fermi surface in pure copper is discussed.
Résumé
La théorie des diagrammes de phase relatifs aux alliages binaires est examinée à la lumière de travaux récents sur la surface de Fermi des métaux nobles. On étudie la relation entre les diagrammes énergie libre/composition et la densité de niveaux, et on revient sur l'explication des règles de Hume-Rothery. On discute les propriétés de la surface de Fermi du cuivre près du centre des faces hexagonales de la zone de Brillouin, la nature de la singularité de la densité de niveaux au point de contact, et la possibilité de réconcilier l'existence d'un contact avec les chaleurs spécifiques expérimentales des alliages de cuivre.
