The novel superelastic Ti-44Zr-10Nb (at.%) alloy was obtained by the vacuum arc remelting method and subjected to homogenization (950 °C, 60 min) and thermomechanical treatment (TMT), which consisted of cold rolling (CR) with a 25% thickness reduction rate and consequent post-deformation annealing (PDA) at 550 °C for 30 min. The analysis of the chemical composition was conducted by the EDS method. It was demonstrated that the obtained chemical composition of the alloy was in good correspondence with the nominal chemical composition. The phase composition of the alloy after TMT was investigated by the XRD technique. The lattice parameters of β and α” phases were measured using XRD data to calculate the crystallographic recovery strain limit. The maximum transformation strain of 7.3% was obtained in the [011] β direction.
