Superplasticity of hydrogen-containing VT6 titanium alloy with a submicrocrystalline structure

Concentration and temperature regimes of hydrogen treatment have been found, which in combination with severe plastic deformation allow one to obtain a microstructure with a size of constituents of about 0.1 μm in the VT6 titanium alloy. It has been shown that the alloy with such a structure has superplastic properties in a temperature range from 500 to 650°C. Characteristics of superplasticity of a hydrogenated submicrocrystalline VT6 alloy and a basic alloy, in which the submicrocrystalline structure was obtained without hydrogen alloying, have been compared. Particular features of a hydrogenated submicrocrystalline VT6 alloy in a superplastic state are considered.
