Low temperature creep behavior around room temperature was examined for coarse-grained (CG) and ultrafine-grained (UFG) aluminum.The materials were fabricated through accumulative roll bonding and subsequent annealing starting from commercial 1050 aluminum sheets, and were provided to tensile tests and creep tests at room temperature.
