Influence of a reverse rotation of the moving striker of a Bridgeman chamber (torsion under high quasi-hydrostatic pressure at room temperature) on the structure and mechanical properties of technically pure titanium (VT 1-0) was studied. It was established that a change in the rotation direction of the moving striker during torsion had a significant effect on the conditions for separating the ω-phase, as well as on the structural characteristics of deformation fragments and dynamically recrystallized grains formed during large plastic deformations. Influence of the deformation method on the internal distortions of structure and on the mechanical properties was analyzed.
