Texture evolution of copper, subjected to multiple compressions in a channel die was studied and interpreted using a simple pure geometric explanation. In this geometric interpretation, deformation in each pass of multiple compressions in a channel die was considered to be analogous to that of flat rolling. After each pass of the compressions, the sample is rotated around two mutually perpendicular directions. The locations of the stable texture components of the rolling were determined with respect to the new sample frame after each pass. In this approach, if the previous stable texture component locates in the stable position in the current pressing pass, this position is considered as the stable texture component position; otherwise, these components rotate into more stable ones. In addition, texture evolution for even passes were predicted via the modified Taylor model which correlate with that estimated by the proposed pure geometric texture evolution explanation and show good agreement with experiments.
