Abstract : The concept of superplasticity, as the state of a sample extended by tensile stress to a very high elongation, requires a more precise definition. The final stage of superplastic flow, followed by true superplasticity, is developed under near zero stresses (less than 0.025 kg per mm squared). The experimental data indicates that super-plastic flow is a common phenomenon during plastic deformation of metals and alloys. The appearance and development of superplastic flow in metals and alloys is controlled by numerous factors, which determine whether the phenomenon may appear and may be absent. The development of superplastic flow (moment of its appearance and its duration) are controlled by such factors as preliminary and acting deformation, temp., and others which promoted its appearance.
