摘要：
A procedure of thermo-mechanical treatment (TMT) was carried out to 2519 aluminum alloy to improve its properties. The influences of cold deformation ratio, ageing temperature and ageing time of the TMT on the mechanical properties and electrochemical corrosion resistance of this alloy were investigated. The results show that after TMT the tensile strength of 2519 aluminum alloy can be improved obviously but its electrochemical corrosion resistance decreases slightly. The optimum processing parameters of the TMT for 2519 aluminum alloy can be described as: solid solution at 530 degrees C for 0.5h, then cold deform with a ratio of 15% followed by aging at 150 degrees C for 10h.
