The textural development and flow stress have been determined in compression and tension of copper (99.999%). For strains below 1.4 (compression) and 1.0 (tension) the textural development is in qualitative agreement with Taylor-model predictions, i.e. a maximum concentration at the 110 and 111 + 100 orientations for compression and tension, respectively. The grain size (23 and 125 μm) has only a relatively small effect on the textural development. For large strains 1.4–2.9 (compression) the textural development is in broad agreement with relaxed-constraints (RC) model predictions. In the strain range where the Taylor-model is prevalent the textural development has only a small effect on the M-factor, i.e. on the flow stress–strain relationship.
