AB The effects of aging treatment temperature of 250°C on microstructure, mechanical properties characteristics of 6111 aluminum alloy sheet were investigated by mechanical testing, scanning electron microscopy, electron backscatter diffraction and other analytical methods. The results show that the aging treatment temperature has a significant effect on the yield strength of cold rolled 6111 aluminum alloy, and appropriate heat treatment can significantly improve the work-hardening properties of rolled 6111 aluminum alloy. The rolled sheet without heat treatment aging shows the highest strength values, with the yield strength reaching 140.2 MPa and the tensile strength 211.2 MPa, while the ten-sile strength decreases to 119.2 MPa and the yield strength to 35.1 MPa when the heat treatment aging temperature of the cold-rolled sheet is set at 250°C. In terms of the plastic behavior of the sheet, the elongation reaches a maximum value of 31.3% when aging at 250°C. The elongation of the cold-rolled aluminum alloy reaches a maximum value of 31.3% when aging at 250 °C. The elongation reached the maximum value of 31.3% at the aging temperature of 250°C.
