A commercial purity aluminum (JIS A1050) and a Al-Mg alloy (A5052) strips 1.94 mm in thickness and 20 mm in width were rolled and annealed. The lateral spread in rolling was varied by rolling methods. The satellite-mill rolling, a conventional caliber rolling and a conventional flat rolling were applied. The pole figures and mechanical properties of strips were measured. Deep drawing of the annealed strips was conducted, and earing of drawn cups were observed. The infuence of lateral spread in rolling on the textures and on mechanical properties of the strips were investigated.
The main results obtained were as follows. (1) The rolling texture approaches fiber texture ⟨110⟩\varparallelN.D. with increasing lateral spread. (2) In the recrystallization textures, the ⟨100⟩{001} cube texture components decreased with lateral spread, (3) The earing height of the drawn cups decreased with lateral spread, These results means that the planar anisotoropy of strips decreased with the lateral spread in rolling.
