摘要：
The effect of final thermo-mechanical treatment on the microstructure and property of Al-5.2Mg-3.1Zn (mass fraction, %) aluminum alloy was studied. The effect of deformation parameter on the final aging treatment was studied by Vickers hardness tests. Observations under optical microscopy and transmission electron microscopy show that there are lots of dislocation structure and fibrous structure in the microstructure, and their volume fractions depend on the deformation parameter. The tensile test reveals that the increase of deformation temperature increases the strength of sheets, but decreases the elongation. However, the amount of deformation has the completely opposite effect on the tensile property. The increase of deformation temperature and deformation amount both increase the intergranular corrosion resistance of sheets.
