Abstract The influence of an intermediate heat treatment at the end hot rolling and before cold on Cube texture formation during final solution annealing AA 6016 is investigated. Three bands with different initial grain sizes textures are considered: first one without rolling, while other two treated 540 °C for 1 hour in air being rolled. One heat-treated was left to cool down inside furnace. Electron-backscatter diffraction (EBSD) maps cold-rolled specimens crystal plasticity simulations show no difference amount remaining microstructure all three specimens. size band has fraction thickness reductions higher than 65 pct. Nevertheless, affects shape distribution grains kernel average misorientation Moreover, decreases intensity beta fiber components (Brass, Copper, S) promotes a low misorientation. Both these factors lower probability preferential nucleation keep volume after recrystallization below 10 pct, it reaches 25 pct annealing.
