Bulk Hydrostatic Properties of Binary Liquid Alloys

The energetic and ground state structures of the elemental metals combined with density- functional theory and the local density approximation now able not only the computation of the cohesive energy of the elemental metals but also the particular symmetry of the ground-state lattice Previously it has been shown that a model based on the electron gas explains the trends in the cohesive energies of the elemental metals. In this paper we show that a simple extension of this uniform electron gas model also explains the trends in the elastic constants of the simple and transition metals and binary alloys at different concentration
