Abstract : The problems are treated in the current report. The first, relevant to dilute metallic alloys, is concerned with the treatment of relaxation round impurities in metals. A synthesis is achieved between the method of lattice statics, which replaces the effect of the impurity by a set of Kanzaki forces acting on all other atoms in the crystal, and electron theory, which characterizes the impurity by the charge it displaces. Secondly, the theory of the influence of order on electron states in metals, described in the last Final Technical Report (AD 693 889), is applied here to calculate the electrical conductivity of a liquid metal. The theory is valid for strong scattering. It contains the Ziman theory, which is recovered when one passes to the limit of weak scattering. (Author)
