Abstract
Microstructures formed in specimens of 1050 aluminum cold-rolled at about 80% and 95% with large draughts and small draughts were observed using SEM-EBSD system. Cold-rolling was carried out using bright rolls without lubrication. Surface textures were formed near the surfaces of the specimens cold-rolled with large draughts up to about 80%. After annealing at 773 K, recrystallized grains having near 〈111〉//ND were formed. When the specimen was cold-rolled with large draughts up to about 95%, such recrystallized grains were not so frequently formed after annealing, although the surface textures had been formed. Whether the recrystallized microstructures having {111} plane orientations are formed or not would not be directly inquired about macroscopic deformation textures. There would be a desirable distribution of {111} oriented dislocation cells and others in deformation microstructures.
