摘要：
Combining high-pressure heat treatment (HPHT) and artificial aging synergistically enhances the mechanical properties and corrosion resistance of high-Li-content Al-Cu-Li alloys. This study demonstrates that HPHT increases the solubility of Cu in the matrix, reducing intermetallic phase volume and promoting the precipitation of nanoprecipitates that strengthen the alloy. Additionally, it decreases micro-galvanic corrosion between intermetallic phases and the matrix, lowering the corrosion current density by three orders of magnitude compared to the T6-tempered sample, while also enhancing intergranular corrosion (IGC) resistance. Applying HPHT and artificial aging to high-Li-content Al-Cu-Li alloys effectively addresses the strength-corrosion trade-off.
