Formation of a single, rotated-Brass {1 1 0}< 5 5 6> texture by hot cross-rolling of an Al–Zn–Mg–Cu–Zr alloy

摘要: The present work describes the evolution of a strong, single-component rotated-Brass ({110}〈556〉) texture in an Al–Zn–Mg–Cu–Zr alloy by an uneven hot cross-rolling with frequent interpass annealing. This texture development is unique because hot rolling of aluminum alloys results in orientation distribution along the “β-fibre”. It has been demonstrated that the deformation by cross-rolling of a partially recrystallized grain structure having rotated-Cube and Goss orientations, and the recrystallization resistance of near-Brass-oriented elongated grains play a critical role in development of this texture.
