7005 aluminum alloy heat treatment process

7005 aluminum alloy heat treatment process
Through the determination of mechanical properties and stress corrosion resistance, the heat treatment process of 7005 aluminum alloy has been studied. The results show that the ideal heat treatment system for this alloy is 470 ℃ solution treatment followed by water quenching, and the artificial aging system is two-stage aging 100 ℃ ×8 h +120 ℃×24 h. After heat treatment, the room temperature tensile strength of the alloy reaches more than 400 MPa, the corrosion resistance is good, and the precipitates are fine and dispersed, which has a good strengthening effect on the alloy.
