Under certain extent of strain, the specimen deformed at a high strainrate has less cavity and higher residual strength than that at low strain rate. Whiledeformation 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 strengthin comparison with that of a single stage. The relationship among residual strength, cavitationand superplastic tensile conditions has been discussed by considering the deformation-in-duced continuous recrystallization occurred during the initial stage of superplasticdeformation.
