초록

Formability and other mechanical properties of sheet metals are strongly dependent on the texture. It was studied to improve the formability of the Al alloy(AA3003) sheets which were rolled under the non-lubrication condition and subsequent heat treated. In the non-lubrication rolled and subsequent heat treated Al alloy sheet, the variation of the plastic strain ratios were investigated in this study. Non-lubrication rolled Al sheets showed a fine grain size and after subsequent heat treated specimens showed that the $\beta$-fiber texture component was increased. The plastic strain ratios of the non-lubrication rolled and subsequent heat treated Al alloy sheets were about two times higher than those of the original Al sheets. These could be related to the formation of $\beta$-fiber texture components through the non-lubrication rolling and subsequent heat treatment in Al sheet.
