Grains in f.c.c. polycrystals deform non-uniformly even under imposed homogeneous deformation and subdivide into domains of different lattice orientations. Intense non-uniformity of grain deformation produces substructural features called deformation bands and shear bands, wherein large deviations from the average lattice orientation and/or slip localization occur. Using a model of grain banding, subdivision of pure copper grains initially oriented along the α,β and τ fibers of the copper-type f.c.c. rolling texture under imposed homogeneous plane strain deformation is characterized. The microtexture developed in grains of these lattice orientations is predicted. The predicted banding response and microtexture quantitatively agree with experimental observations reported in the literature. © 2013 Elsevier Ltd. All rights reserved.
