The evolution of the recrystallized structure and texture of a cold-rolled Al-Mn-Mg alloy with different heat treatments was studied. The alloy with dual-heat treatments at 872 K and 644 K (599 C and 371 C) exhibited fast recrystallization and had coarser recrystallized grains and stronger cube texture than the alloy with single-heat treatment at 872 K (599 C). The differences in microstructures and textures were attributed to the precipitation state. Large particles formed during annealing at 872 K (599 C) played a randomizing effect on the total recrystallization texture, while smaller particles formed during annealing at 644 K (371 C) not only enhanced recrystallization of the cold-rolled sheets, but also caused formation of coarse, recrystallized grains with a strong cube texture. The evolution of the coarse grains was due to nucleation of cube-oriented grains.
