| Abstract: | The mechanical properties and microstructure characteristics of 8090 aluminum-lithium alloy have been investigated extensively by tensile testing, transmission and scanning electron microscopy in different heat treatment cinditions. The results showed that the optimum properties were obtained at 165℃/70-80h in which temper a better matching between δ' and S'precipatates was obtained, and the growth of δ' and δ' （PFZ） was limited. |
