The Calculated and Experimental Elastic Properties of Quenched Biocompatible Ti-Nb, Ti-Nb-Zr, Ti-Nb-Zr-Sn, and Ti-Nb-Zr-Sn-Ta Titanium Alloys

The results of calculations of the elastic properties of quenched biocompatible titanium based Ti-26% Nb, Ti-26% Nb-3% Zr, Ti-26% Nb-6% Zr, Ti-26% Nb-3% Zr-1%Sn, and Ti-26% Nb-3% Zr-1% Sn-0.7Ta alloys (in at %) are presented and compared with the literature and experimental data on estimating the elasticity modulus of alloys by microindentation. Microstructural and X-ray diffraction analysis showed that the studied alloys subjected to quenching from the beta-region contain a single-phase metastable solid beta-solution prone to twinning under cold deformation as follows from the location of the alloys in the B-o-M-d diagram. Good agreement has been established between the calculated and experimental values of the elastic properties, as characterized by an increase in the shear and Young moduli and a decrease in the Poisson coefficient with an increase in the molybdenum equivalent, which determines the stability of a solid alloy beta-solution.

Automated summary

The elastic properties of quenched biocompatible titanium-based alloys were calculated and compared with literature and experimental data. The study showed that an increase in the molybdenum equivalent led to an increase in the shear and Young moduli and a decrease in the Poisson coefficient, indicating the stability of the solid alloy beta-solution.
