Abstract In this paper, we compared elastic shear moduli determined by EMAT techniques to x-ray pole figure measurements for three lots of rolled copper sheet. All moduli (C′44,C′55,C′66) decreased with rolling reduction to more than −10% for a 90% rolling reduction and the difference betweenC 44 andC 55 increased with developing in-plane anisotropy as predicted in Part 1. Pole figures of (111) and (200) planes revealed various initial textures for the starting annealed plates, and (111) pole rotation toward a single well-defined preferred orientation at large rolling reductions. Stress relief annealing of a heavily cold rolled plate produced no significant changes in elastic moduli while hardness decreased, thus indicating that textural changes were responsible for the observed moduli changes.
