Abstract

We studied the effect of the ultrafine-grained (UFG) structure parameters of the titanium alloy Ti-6Al-4V, processed by high-presure torsion (HPT), on its mechanical properties. The fabrication of alloy with a high strength (σв ~ 1700 MPa) and enhanced ductility was demonstrated. The fatique behavior of UFG alloy was also examined.
