On the Anisotropy of Electrical Resistivity of Deformed Cubic Metals and Alloys

Abstract

The change of resistivity on annealing cold-rolled metals has been found to depend on the direction of measurement for copper-nickel, steel, cc brass, and sterling silver, while no such variation was observed for aluminium, copper, or nickel. An explanation of anisotropy both in strip and in wire is advanced in terms of lattice disturbances such as dislocations, vacant sites, and faults, some of which can give rise to anisotropy of resistivity when there is a preferred orientation of crystals. Results are presented showing the influences of deformation, recovery, and a second phase on the anisotropy developed in brasses.
