Abstract

Cryogenic rolling combined with warm rolling has been found more effective than a single cryogenic rolling process in improving the strength of a 5052 Al alloy. In this study, cryo-rolled 5052 Al alloys were warm-rolled at $175^{\circ}C$. A notable increase of tensile strength was achieved by the precipitation during warm rolling process. Mechanical behavior of this alloy was investigated using hardness and tensile tests. It was found that the cryogenic rolling process combined with warm rolling process was very effective in improving tensile strength.
