MICROSTRUCTURAL EVOLUTION OF COLUMNAR GRAIN Al DURING COLD ROLLING I. Marcoscopic Subdivision
柱状晶Al在冷轧过程中微观组织演变的定量表征Ⅰ宏观分裂

Columnar grain Al samples with {001}{uv0} orientations were cold rolled to reductions of 10%, 30% and 50%, respectively. The macroscopic subdivision of grains with different orientations was characterized in detail by using EBSP technique. It is found that the macroscopic subdivision patterns of different oriented grains are different. A model based on dislocation slip was used to analyze the observed macroscopic subdivision patterns.
