The dislocation slips during the hot- and cold-rolling processes, the texture evolution and the Goss-oriented grain refinement during the annealing of the Al-Cu-Mg alloy were investigated using optical microscope (OM), scanning electron microscope (SEM), electron back-scatter diffraction (EBSD), transmission electron microscope (TEM) and X-ray diffraction (XRD). Results shown that {111} <110> octahedral slip systems and {110} <111> non-octahedral slip systems can be activated during the hot- and cold-rolling. When the dislocation slips in {111} planes are suppressed, the cross-slip from the {111} planes to the {110} planes can be activated to coordinate deformation. The strain gradients between the adjacent grains of the alloy with the large cold rolling reduction during annealing are dramatically decreased by the strain homogenization, which suppresses the growth of {110} < 001 > Goss-oriented grains. The activation of {110} <111> slip systems may be led to the decrease of the intensity of {112} <111> Copper texture, and the effect of {110} <111> slip systems on the evolution of {001} < 100 > Cube texture is very small. With the increase of the cold rolling reduction and annealing temperature, the hardness of the annealed and rolled Al-Cu-Mg alloy all increases, strain hardening and grain refinement are responsible for the enhanced hardness.
