Abstract
A pseudo-α PT3V titanium alloy with a grain size of about 10 μm is shown to demonstrate all evidence of superplasticity in the temperature range 880–920°C during tensile deformation at a strain rate of 10–3–10–2 s–1: the relative elongation is higher than 300% and the strain-hardening exponent is higher than 0.4. It is concluded that the use of isothermal stamping of bottom-type parts from the titanium alloy in the superplastic state is profitable.
