The behavior of texture formation in AA5182 aluminum alloy was investigated by uniaxial compression tests under strain rates and temperatures ranging from 5.0 × 10^-4s^-1 to 5.0 × 10^-2s^-1 and from 673K to 823K, respectively. After the deformation, {011} (compression plane) or {001} fiber texture appears. It was found that {001} fiber texture was formed after the development of {011} fiber texture. The size of {001} grains is larger than the average grain size, suggesting that the {001} texture formation is attributed to grain boundary migration. In order to understand the relationship between texture sharpness of {011}, temperature and strain rate, the texture map is proposed. The {001} texture map elucidates that the balance between flow stress and deformation temperature is important for the development of {001} component when the viscous motion of dislocation is the dominant deformation mechanism.
