Development of Deformation Textures in Polycrystalline Copper Experiments and Model Predictions

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 μ m) 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.
