Abstract
High strength aluminum alloys will enhancing mechanical properties always plays a major role in controlling microstructure of cast and processed alloy. The desire for more efficient aircraft materials has fueled research of aluminum AA-2xxx and AA7xxx alloys. In these alloys were rolled at cold rolling and at cryorolling to 80 % thickness reductions and an attempt was made to evaluate the optical-microstructural variation and the variation in tensile properties of these aluminum alloys. Cryorolled alloy also exhibited better hardness and strength compared to cold alloy due to suppressed thermal recovery. Coldrolled alloy showed more necking percentage compared to cryorolled for rolling reductions of 80% and more formability was observed.
