Concentrated solid solutions of normal metals

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
