    Abstract:

    The structures and mechanical properties of a new super-high strength Al-Li alloy developed by this group were investigated. The alloy possessed excellent properties, of which the tensile strength was greater than 600 MPa, and the elongation higher than 10%. After T8 aging, the strengthening precipitates in both cold-rolled sheet with 2 mm thickness and hot-rolled plate with 10 mm thickness were T1(Al2CuLi) and q￠(Al2Cu), and their fraction and size were basically same in the two plates with different thickness. The strength of T8-aged plate with 10 mm thickness was 50~70 MPa higher than that the T8-aged sheet with 2 mm thickness. This strength enhancement was originated from the texture fraction after solution treatment. The volume fraction of the deformation texture in the solutionized hot-rolled plate with 10 mm thickness was much higher.
