Abstract

The article examines the microstructure, phase composition, mechanical properties, and fracture mechanism of titanium alloys of the Ti–Zr–Nb system with the addition of silver. The elemental composition of the system was selected from non-toxic elements that can provide a level of mechanical properties at the same level as Ti–6Al–4V, but with a lower Young’s modulus to eliminate the “stress shielding” effect. Samples of the TiZr38Nb11 alloy and its modifications with the addition of silver (1–3 at %)) were obtained by melting in an argon furnace, followed by annealing and quenching to obtain a uniform structure. A study of the alloys showed that the lowest Young’s modulus (48 MPa), maximum strength (748–778 MPa), and microhardness (292 HV) were achieved with a silver content of 3% (TiZr38Nb11Ag3).
