Ti-40wt.% Nb alloy in UFG state (structural elements’ average size is 0.28 μm) has multiphase structure, which is represented by β-subgrains, dispersive-strengthened with nanoparticles of nanosized ω-phase, and α-subgrains. Annealing temperature range of 773-973 K is characterized by transformation of alloy’s structure from ultrafingerained state into finegrained, active growth of dispersive-strengthened β-phase’s grains size and significant decrease of microhardness. Transformation occurs according to the α→β scheme.

It has been established that under shear deformation during SHS extrusion, the modification of Ti – B – Fe with small additions of nano-sized aluminum nitride powder leads to the refinement of the grain structure of the material. As a result of a decrease in the grain of the main phase, the microhardness of the material increases, on average, by 10%.

The superelasticity at stress-induced α–γ'-martensitic transformation at room temperature in compression was 6.2 % and 5 % in [001]-oriented Fe43.5Mn34Al15Ni7.5 (at. %) single crystals and Fe42.5Mn34Al15Ni7.5Ti1 (at.%) oligocrystals, respectively. Single crystals exhibited good stability of superelasticity in isothermal loading/unloading cycles, in contrast to oligocrystals.
