“…At a specimen temperature of 800°C, the pro- cesses related to recrystallization are initiated, the disperse particles at the grain boundaries are increased, and the yield stress sharply drops; herewith, the role of the strain rates increases. The combination of axial deformation with torsion allows us to decrease significantly the tool load and increases the homogeneity of the ultrafine structure [8][9][10]. The selection of the temperature rate regime of deformation provides favorable conditions for shape variation of the analyzed material (Table 2, specimens 10, 11, 12).…”

The development of a rheological model of the OT4-1 titanium alloy by upsetting specimens at the strain rates = 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.
