The physical and mechanical properties and formability of sheet metals depend on preferred crystallographic rientations (texture). In this research work, the texture development and formability (plastic strain ratios) of AAI050 Al lloy sheets after 3 and 10 passes of asymmetric rolling and subsequent heat treatment were investigated. The plastic train ratios of 10 passes asymmetrically rolled and subsequent heat treated samples are 1.3 times higher than those of the nitial AAI050 Al alloy sheets. The L'lr of 10 passes of asymmetrically rolled and subsequent heat treated samples is 1/30 imes lower than those of the initial AAI050 Al alloy sheets. The plastic strain ratios of 10 passes of asymmetrically rolled nd subsequent heat treated Al sheets are higher than those of 3 passes ones. These results could be attributed to the ormation ofy-fiber, ND//, and the other texture components by means of asymmetric rolling in Al sheets.
