Abstract
An elementary discussion is presented of how the atomic disorder near a dislocation line can produce enough large-angle scattering to account for the measured values of electrical resistivity in metals. The anisotropy of conduction electron scattering over the Fermi surface is deduced from analysis of the model. The values of specific dislocation resistivity calculated in different metals generally agree well with measured values. There is some comment on the broad trend of resistivity values in different metals produced by dislocations, which is similar to the trend of phonon-produced resistivity. A critique of certain other theoretical models is also presented.
