In the present research paper, two systems based on Ti-Nb-Zr-Ta and Ti-Nb-Zr–Fe, containing non-toxic elements, are considered and investigated. The first aim of the paper is to enlarge up-to-date developed β-type Ti alloys, analyzing three different compositions, Ti-10Nb-10Zr-5Ta, Ti-20Nb-20Zr-4Ta and Ti-29.3Nb-13.6Zr-1.9Fe, in order to assess their further employment in biomedical applications. To achieve this, structural, microstructural, compositional and mechanical investigations were performed as part of this study. Based on the results obtained, the alloy with the highest Nb content seems to be the most appropriate candidate for advanced biomedical applications and, in particular, for bone substitution. |
