摘要：

Employing the recently established polycrystal plasticity grain fragmentation model (GR) under an updated version, the pixel-to-pixel disorientation axis distribution (DAD) was examined for copper deformed by 90 degrees equal-channel angular pressing up to two passes at room temperature. It was found that the disorientation axes are preferentially parallel to the transverse deformation axis. The GR model reproduced faithfully the DAD together with other microstructure features including grain size distribution and disorientation angle distribution. (C) 2013 Acta Materialia Inc.
