In this work, the following are investigated: structure, phase composition and mechanical properties under static tension of titanium alloys Ti–(36–40)Zr–9Ta (at %) for medical use after hot rolling and quenching. After rolling, the alloys consist of α'- and β-phases. The results of the research show that the hardening of alloys leads to the almost complete dissolution of the β-phase and the release of α'- and α"-phases. Investigations of mechanical properties of alloys Ti–(36–40)Zr–9Ta (at %) show that, in terms of tensile strength, the studied alloys Ti–36Zr–9Ta, Ti–38Zr–9Ta, and Ti–40Zr–9Ta are similar to the VT6 alloy widely used for implants (σ = 835–1100 MPa), and, in terms of plasticity (δ = 15–21%) and low value of Young’s modulus ( E = 53–73 GPa), significantly exceeds it.
