In this paper, the authors compared elastic shear moduli determined by EMAT techniques to x-ray pole figure measurements for three lots of rolled copper sheet. All moduli (C'/sub 44/, C'/sub 55/, C'/sub 56/) decreased with rolling reduction to more than -10% for a 90% rolling reduction and the difference between C/sub 44/ and C/sub 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.
