Superplastic forming (SPF) is an effective process that allows for forming the sheet metal parts of complex configuration. Superplastic deformation behavior of conventional sheets of a high temperature titanium alloys VT8 и Ti6242S was studied by constant strain rate tests in a temperature range of 850–950 ∘C. The research identified the optimum superplastic temperature of studied alloys in a constant strain rate of 3 × 10−4 s −1 with elongation above 150 %.

Keywords: superplasticity, titanium alloys, stress, elongation.
