Abstract
A discussion of recent works using the CPA and ATA theory of electrical conductivity of alloys at finite temperature yields an expression for the resistivity which is consistent with a general analysis of the influence of the coupling between thermal and configuration disorder in metallic systems. It emphasizes the importance of band broadening induced by phonon or spin fluctuation disorder on the T-dependence of the resistivity and appears as an alternative model to describe the resistivity of crystalline, liquid or amorphous alloys when the Fermi level lies in a d or f density of states peak
