%X In this paper,a study on superplastic deformation process was conducted on anunpretreated cold-rolled Al-Li-Cu-Mg-Zr alloy based on the concept of three-stage tension.The experimental results of superplastic tensile test carried out according to orthonormal designshow that,for cold-rolled Al-Li alloy,better superplasticity can be obtained by usingthree-stage tension process.Its elongation can reach 550% which is higher than that forone-stage or two-stage tension process.
