The 3104 aluminum alloy treated by hot tandem mills at different finish rolling temperature (FRT) was taken as the samples in the experiment to investigate the effect of FRT on its microstructure and texture evolution during the subsequent cold rolling and intermediate annealing processes. It is found that as the FRT for the 3104 aluminum alloy sample rises, the hot-rolled sheet presents highly recrystallization level, with increased volume fraction of Cube texture and decreased volume fractions of Brass, S and Copper textures. Furthermore, as FRT rises, the average grain size of the intermediate annealed sheet increases, and also the volume fraction of Cube texture in the cold-rolled sheet before intermediate annealing process increases, which is unfavorable for the formation of a strong Cube texture after annealing. As a result, the volume fraction of Cube texture in the final cold-rolled sheet decreases.
