Increasing the Strength of Commercial Titanium VT1–0 Using the Method of Severe Plastic Deformation

Abstract

The problem of reduction of the mass of parts due to an increase in the strength characteristics of the material of these parts by forming an ultrafine grain structure using the method of combined severe deformation including multiaxial forging with further upsetting with torsion is solved. The results of mechanical tensile tests and metallographic tests of titanium are presented, as are the thermal processing modes increasing the plasticity while keeping sufficiently high strength characteristics, which allow selecting the thermomechanical processing parameters required for a certain article.
