| Abstract: | The effects of two-peak aging treatment on microstructure and mechanical properties of 7055 aluminum alloy were investigated. Results indicate when the peak quantity property of 7055 aluminum alloy property turn up, two-peak aging treatment is 135 ℃/16h＋ 190℃/10min. Then, the yield strength is 695 MPa,the ultimate strength is 658 MPa ,and the elongation is 14%. |
