Abstract: The recrystallization behaviors of severely cold-rolled A1050 thin sheets (100 μm thick) with a reduction area of98.3% were examined in detail. The thin sheets consisted of elongated and banded grain structures with typicalβ-fiber (Brass-S-Copper) texture components. Based on electron backscatter diffraction (EBSD), microstructuralfeatures such as misorientation measures of the kernel average misorientation (KAM) and grain boundary informationof the lattice misorientation angle and axis were characterized. The elongated grains with representative orientationsnear Copper and S components possessed slightly greater KAM values than those near Brass. During annealing,newly recrystallized grains mainly contained the representative orientations near Copper and S, as opposed to Brass.Low angle grain boundaries (LAGB) observed between the recrystallized and deformed β-fiber grains revealed theoccurrence of subgrain growth. The typical recrystallization Cube and Goss textures were also found during annealing.An equi-axed Cube grain growing inside deformed grains with the representative orientation near Copper revealswidespread grain boundary misorientation. An ellipsoidal Goss texture grows up along the two deformed bands withequivalent near-S orientations. One band is mainly consumed by Goss, and the other band prevents it from growinginward by means of grain boundaries with 60◦ 〈111〉. Various grain boundary misorientations reveal the dynamicevolution of the newly recrystallized grains.
