In the present paper, we have developed an effective thermal-mechanical process for achieving both high strength and good ductility in a spark plasma sintered Al 2024 alloy. After conventional solid solution treatment, room temperature cold rolling and artificial aging at 175 掳C for 3 h, the engineering yield strength and ultimate tensile strength of the Al2024 alloy are 529.6 and 583.1 MPa, respectively, while maintaining a remarkable elongation to failure of 16.2%. The superior of the mechanical properties was discussed.
