Influence of the Temperature of Straining in a Bridgman Chamber on Peculiarities of the Defect Structure Formation in Commercial-Grade Titanium

Transmission electron microscopy data showed evidence of the formation of structural regions corresponding to deformation (dislocated) fragments and dynamically recrystallized grains in α-phase titanium upon torsion at high hydrostatic pressure at room and cryogenic temperatures. It is shown that the previously proposed “two-phase mixture” model is applicable to description of these defect structures.
