Abstract

Research was done on the mechanisms of strengthening underlying the mechanical characteristics of AA5052, as well as the effects of room-temperature rolling (RTR) and cryogenic rolling (CR). The results show that cryo-processing AA 5052 significantly reduces the size of second-stage and sub-grain particles in addition to increasing dislocation density. When compared to RTR, CR processing considerably improves the ultimate tensile strength (UTS), yield strength (YS), and elongation (El) of AA 5052. This is because of the synergistic effects of a finer grain structure and increased strength from dislocations.
