Abstract
In order to study the formation of deformation bands (DBs) and its relation to recrystallization, an aluminum single crystal was compressed along the ⟨011⟩ direction and subsequently annealed. In the present crystal, the four slip systems having the largest Schmid factors were on two slip planes that were symmetrically arranged with respect to the direction of observation. The overall deformation was consistent with the arrangement of these two major slip planes. In the central region of the observed surface, the major slip planes were activated to form a double-slip pattern. On the other hand, at the corner regions, many DBs were formed. After annealing, recrystallization occurred in the regions containing the DBs. Recrystallized grains had a ⟨111⟩-rotation relationship with the DBs. The experimental results were compared with those in tensile-deformed aluminum single crystals having the same crystallographic orientation.
