Abstract

Lattice energy functions have been used to predict various properties. The energies and volumes of formation of alloy phases, as well as the relative stabilities of competing phases are provided by a model based on Mie type interatomic potentials. The elastic constants of alloy phases are treated using a model sensitive to the quadrupole distortion of a repulsion spheroid. The properties of defects are treated using a model based on both a volume dependent contribution and an interatomic potential contribution to the lattice energy. Good predictability is obtained for all three types of lattice energy functions in their respective applications.
