Texture development in Al-high Mg alloys during recrystallization and grain growth

Al-high Mg alloys containing Mg more than 6% were cold rolled 95% and annealed at temperatures between 275 and 450degreesC. Textures developed in these alloys were investigated with the orientation distribution function analysis. It was found that the heating rate to the annealing temperature strongly influenced the annealing textures of these alloys. Annealing with the slow heating rate resulted in the development of {100}<001>, whereas annealing with the rapid heating rate enhanced the development of {100}<013> and {103}<321>. This is because the orientation distribution established at complete recrystallization had strong influences on the texture development during subsequent grain growth. Annealing textures in the Al-9% Mg alloy were always random, since its rolling textures were random.
