Abstract—

The development of a rheological model of the OT4-1 titanium alloy by upsetting specimens at the strain rates \({{\dot {\varepsilon }}}\) = 10–1, 10–2, and 10–3 s–1 in air at constant temperature under isothermal conditions in the range of 20–800°C using the empirical model proposed by Hensel–Spittel is discussed. The correctness of the determined dependence has been shown on the basis of its application for simulation of upsetting processes with and without torsion of cylindrical specimens from the OT4-1 alloy using the QForm 9.0.8 program.
