Abstract

The melting temperature of pure metals is calculated as a function of the relative volume. The calculation of pressure-temperature phase diagrams and of composition-temperature phase diagrams is discussed. The systematics of the distribution of the melting temperatures of binary metallic compounds and alloys are considered. Ion-core pseudopotentials have been derived through full-core atom calculations based on the Dirac equation and the points of minimum and the points of maximum curvature of these have been plotted as a function of the distance from the centre of the atom. The systematics, evident in the plots, allows a theoretical prediction of the magnitude of the melting temperatures.
