Crystallographic texture evolution of continuous cast Al–Mn–Mg alloy sheet during cold rolling and annealing

Development of crystallographic texture of continuous cast (CC) Al–Mn–Mg alloy sheet during cold rolling and annealing was studied. We showed that the Cube orientation {0 0 1}〈1 0 0〉 is the major recrystallization texture of the hot rolled CC Al–Mn–Mg alloy sheet with intermediate heat-treatment (IHT). Nevertheless, we were somewhat surprised to find that the P orientation {0 1 1}〈5 6 6〉 is the dominant recrystallization texture of the hot rolled CC Al–Mn–Mg alloy sheet without the IHT. essed the earing tendency of the P orientation {0 1 1}〈5 6 6〉 using a modified Tucker model. The simulation results showed that the P orientation {0 1 1}〈5 6 6〉 leads to 30°/60° earing, which exhibits the same earing behavior as deformation textures such as the Copper {1 1 2}〈1 1 1〉, S {1 2 3}〈6 3 4〉, and Brass {0 1 1}〈2 1 1〉 orientations. These results lead us to believe that, even after complete recrystallization, the 45° earing could remain somewhat pronounced for CC Al–Mn–Mg sheets without the IHT.
