Biomechanical compatibility of a Ti-(20-30) Nb-5Zr shape memory alloy was studied. The tensile strength study was carried out. The best properties are observed for the Ti-28Nb-5Zr composition with a wire diameter of 1200 μm, adapted to work in a living organism. The dependence of the change in strength and plasticity on the annealing temperature exhibits minimal extrema. The best characteristics are noted at 800 °C.
