Abstract

In this study, the textures and microstructures of Al–5%Mg after cold rolling 95% and recrystallization at 300 and 450 °C have been investigated. The cold rolling textures were typical but the recrystallization textures at 300 °C comprised Cube and S and at 450 °C, Cube, ND Rotated Cube plus a weak Q component. The deformed grains were wavy in the longitudinal section as a result of composite-like behaviour, and the narrowed regions had scattered orientations which weakened the final annealing texture. Another feature was grains dividing into their respective crystallographic complements. S grains frequently behaved in this way and nucleation of S-oriented recrystallized material at low temperature was common. Cube-oriented volumes were often found between complementary S volumes, and this favoured micro-growth selection and a detailed discussion of the Cube origins are given. Remarkably, recrystallization texture is largely determined by the behaviour of S- and Cube-oriented material.
