Abstract

The effects of microstructures such as textures, grain boundaries, and second phases on the anisotropy of roll casting strips of cold rolled 3003 aluminum alloy were studied by OM, TEM, EBSD, and uniaxial tensile test. The results showed that the tensile strengths of the specimen along the rolling direction (RD), 45° direction to the RD (AD) and the transverse directions (TD) are 181.0, 159.1, and 190.0 MPa, respectively. Planar anisotropy indexes of up to 10.5 for the tensile strength seems attributable to textures S{123}<634> and copper{112}<111> in the strip. However, based on weighted calculations with a Schmid factor, the maximum strengthening effect appears along the RD caused by the textures, while less strengthening effect along the AD is less, and minimal effect along the TD. Band grains along the RD induce a higher grain boundary density as compared to the AD and TD. These band grains contribute to the maximum strengthening effect in the RD and the correspondingly lower strengthening in the AD. The anisotropy of 3003 aluminum alloy strips is related to the cooperative action of texture, grain boundary, and second phase.
