Abstract

The texture development in copper and brass (15% zinc) is followed by neutron-diffraction measurements from the early stage. The texture development is found to be different in the two materials from the very beginning (largely towards the respective final textures of copper and brass). As demonstrated by texture simulation starting with the experimental orientation distributions of the undeformed materials, the early difference in texture development is not a result of the differences in initial texture. The conclusion of the texture measurements—and of earlier microstructural observations confirmed in the present work—is that the development of the brass-type texture cannot be explained by any of the proposed twinning theories. The only existing model capable of reproducing the development of the brass texture at moderate strains without disagreement with experimental observations appears to be the Sachs model, or rather a modified Sachs model.
