Residual resistivities of Ag/sub c/Pd/sub 1-c/ alloys for 0.2< or =c< or = 0.8 were calculated from first principles using the Korringa-Kohn-Rostoker coherent-potential approximation and yielding quantitative agreement with experiment with no adjustable parameters. Some aspects of Mott's sd model are confirmed, but the s sheet velocities and lifetimes vary in a surprising manner with concentration because of the energy dependence of the disorder self-energy at the top of the d-band complex. These variations are analogous to electron-phonon mass and lifetime renormalization.
