%X The residual strength and relation to the cavitation of as-warm rolled Al-Li-Cu-Mg-Zr alloy have been investigated after superplastic deformation under differ- ent tensile conditions. Under certain extent of strain, the specimen deformed at a high strain rate has less cavity and higher residual strength than that at low strain rate. While deformation to a large strain, the specimen deformed under test at strain rates of two-stage, i.e., at a quick one first and slow down afterward, has less cavity and higher residual strength in comparison with that of a single stage. The relationship among residual strength, cavitation and superplastic tensile conditions has been discussed by considering the deformation-in- duced continuous recrystallization occurred during the initial stage of superplastic deformation.
