Recovery and recrystallization were studied in commercial purity aluminum cold rolled to an ultrahigh strain (εvM=6.4) and isothermally annealed at 300°C. The deformed material consists of three layers with similar fractions of high-angle boundaries (HABs) and similar lamellar boundary spacings, but...
