摘要

Ti-6Al-7Nb containing harmless for tissues niobium can be a good choice replacing Ti-6Al-4V for orthopedic implants application. Formation of ultrafine-grained (UFG) structure in metals and alloys by severe plastic deformation (SPD) techniques allows for achieving unique mechanical properties. Using equal channel angular pressing (ECAP) UFG structure in Ti-6Al-7Nb alloy with an average size of grains/subgrains of 200 nm was obtained. This UFG Ti-6Al-7Nb alloy has high mechanical (ultimate tensile strength 1470 MPa) and fatigue properties, suitable for practical application.
