Abstract：To optimize the aging treatment parameters and explore the strengthening and toughing mechanism of aging treatment, the effects of single-stage aging treatment on the microstructure evolution of 6082 extruded aluminum alloy profiles were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD) and electron backscatter diffraction (EBSD). The results show that the aging treatment can effectively reduce the residual stress stored during the extrusion deformation process. The crystalline grain grows slightly with average size increased from 7.02 μm to 9.80 μm. The average crystalline grain boundary angle is decreased from 25.51° to 16.06°, and the low angle grain boundary ratio is markedly increased from 47.91% to 67.47%. The aging treatment can significantly change the grain distribution in the {100} and {110} directions of the crystalline grain, which remarkably enhances the texture of the sample in the {100} and {110} directions. These changes are conducive to the improvement of the performance of 6082 aluminum alloy extruded profiles.
