| description | According to the corrosion-resistant high-strength 7-series aluminum alloy thick plate for the upper wall plate of the large aircraft wing and the preparation method of the corrosion-resistant high-strength 7-series aluminum alloy thick plate, under the conditions that the Zn/Mg element ratio of Al-Zn-Mg-Cu-series alloy is accurately controlled and the quenching sensitivity of the alloy thick plate is reduced, the high-strength 7-series aluminum alloy thick plate is obtained by increasing the heating rate in the process from the end of first-stage low-temperature aging to the second-stage high-temperature regression aging. And three-stage aging parameter optimization of the alloy thick plate is realized, so that the Al-Zn-Mg-Cu series aluminum alloy thick plate with fine dispersed and uniformly-distributed strengthening phases in the crystal, discontinuously-distributed coarse equilibrium phases in the crystal boundary, wide precipitation-free precipitation zone in the crystal boundary, high strength, high fr |
