Texture Evolution in Continuous Casting AA5052 Aluminum Alloy Hot Band During Equi-Biaxial Stretching

In this study, the global texture evolution in a 2 mm gauge hot band of continuous casting AA5052 aluminum alloy, annealed at 449 °C for 4 hours, was investigated. Samples were deformed to three different strain values under a near equi-biaxial stretching condition. Their textures were. The major and minor strains of these samples were measured using an automatic strain analysis system. The texture evolution in the different layers through thickness of these samples was measured using X-ray diffraction. It was found that cube and Goss ({110} 001 ) components varied markedly during biaxial stretching, while brass, copper and S components were changed only slightly. Cube orientation was decreased, whereas Goss orientation was increased, which was more profound in the surface region of the hot band during stretching. A weak fiber-like component, {110} hkl , was developed during biaxial stretching. In addition, a {110} 111 component was also found to exist mainly in the surface.
