Abstract  Columnar grain Al samples with 001uv0 orientations were cold rolled to reductions of 10%, 30% and 50%, respectively. The microscopic subdivision of the matrix bands in grains with different orientations was quantitatively characterized in detail by using EBSP technique. It is found that all the grains are microscopically subdivided into dislocation cell blocks. But the microstructures of differently oriented grains are different after rolling. With increasing strain, the misorientation angles across the dislocation boundaries increase, following a power relationship with an exponent of 2/3. By the Frank formula, the dislocations in the dislocation boundaries are mainly from the slip systems decided by the Schmid factors.
Key words:  columnar grain Al      cold rolling      EBSP
