Abstract: Al 5052 alloy sheets were subjected to different pre-annealing temperatures (150, 200, 250, 300, and 350��C) prior to cryorolling. The process resulted in Al 5052 alloys with different initial microstructures. The pre-annealed alloy sheets were compared with a cryorolled sample not subjected to pre-annealing. The thicknesses of the alloy samples after cryorolling was reduced by 30%. The pre-annealed cryorolled samples exhibited low crystallite size, and high lattice strain. Among them, the cryorolled sample pre-annealed at 300��C had the lowest crystallite size, and the highest lattice strain. Changes in initial microstructure of this sample resulted in a significant improvement in its hardness (88�Hv), tensile strength (333�MPa), and corrosion resistance. The sample had the highest corrosion resistance among the cryorolled samples. � 2018, ASM International.
