The mechanical properties of two-phase Ti-6Al-4V titanium alloy with ultrafine grained microstructure were studied in the present work. Bulk ultrafine grained specimens of the alloy were produced by means of warm “abc” deformation. The final structure consisted of α/β particles with a size of 500 nm. Extensive studies of the mechanical properties of this material in comparison with conventionally heat-strengthened condition were conducted. A room-temperature strength and fatigue resistance of the ultrafine grained material was found to be 25-40% higher than that of heat-strengthened alloy. However such ductility related properties as tensile elongation and impact toughness noticeably decreased with decreasing grain size. Efficacy of ductility improvement and the strength/ductility balance optimization were analyzed.

Strength And Ductility

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.
