Creating the foundations of effective technology for the manufacture of accurate blanks with thin-walled elements from refractory titanium alloys and powder materials for the machine-building and aviation industries is an important technological problem.
The paper considers a promising direction of plastic forming of accurate workpieces based on eutectically strengthened titanium alloys and powder materials. The deformation properties of these materials, which are described by the viscoplastic model of the material, depend on the conditions of formation (temperature, strain rate, initial state of the material, etc.). Therefore, this research is devoted to theoretical analysis direct at predicting the conditions of practical tests for each type and condition of the material. The friction conditions are taken into account in the study, which are determined by the high, in relation to aluminum alloys, adhesive properties of titanium alloys.
The sustainability of the process of plastic flow of metal in the formation of details with thin-walled elements depends on the gradient of the temperature field. Therefore, special attention is given to gaining knowledge about the conditions of control of this temperature field.  Such research is needed to reduce the cost of the technological process at the stage of creating non-standard equipment, namely, installations for isothermal shaping
