Abstract

Twin-roll cast AA3003 series aluminum alloy was subjected to several passes of asymmetric rolling at room temperature. This process is more effective in the grain refinement than conventional cold-rolling. During subsequent annealing at elevated temperatures the deformed grains are replaced by new ones by static recrystallization, which starts near the surfaces of strips. Higher strain imposed by rolling results in a decrease in recrystallization temperature. Nevertheless, the rolling direction remains apparent even after full recrystallization.

Keywords: Twin-roll casting, asymmetric rolling, microhardness, recrystallization
