processes on tensile and corrosion properties of 2A97 Al-Li alloy were investigated. The results show that, undertaken with heat treatment process C (pre-deformation 5%+100 ℃, 1.5 h+mid-deformation 5%+160 ℃, t), the alloy obtains preferable combination of strength and ductility. At the peak-aged condition of heat treatment process C, the tensile strength and elongation of 2A97 Al-Li alloy are 597 MPa......
