The use of materials with a low Young\u2019s modulus ensures the long-term safety of the implant by reducing the stress shielding effect, which causes bone resorption. This work investigates the effect of alloying with niobium in the range of (8\u201310) at. % on the Ti-38Zr alloy, specifically its structure, mechanical properties, Young\u2019s modulus, and superelasticity. In this study, plates of the Ti-38Zr-(8-10)Nb (at. %) alloy were investigated after quenching and subsequent annealing. In Ti-38Zr-(8-10)Nb alloys, quenching from 600 \u00b0C fixes the \u03b2-phase of Ti. In alloys with (8-9)Nb, this is a metastable \u03b2-phase, as evidenced by its superelastic behavior under cyclic tension. Annealing at 400 \u00b0C leads to a clear decomposition of the quenched high-temperature \u03b2-phase in Ti-38Zr-(8-9)Nb alloys into \u03b2- and \u03b1\u2032-phases. Based on the mechanical test results, it can be inferred that the precipitation of the brittle \u03c9-phase and the \u03b1\u2032-phase occur concurrently, since annealing at 400 \u00b0C causes a pronounced embrittlement of the Ti-38Zr-(8\u20139)Nb alloys (with elongation dropping from ~15% to 0.7\u20132.5%, respectively) alongside a substantial increase in strength (from 500 MPa to 1010 MPa). For the Ti-38Zr-10Nb alloy, the ductility also declines but remains within acceptable limits (from ~14% to ~10%), while the strength rises from 520 MPa to 630 MPa. The Young\u2019s modulus of the Ti-38Zr-(8-10)Nb alloy after quenching is ~80 GPa. After annealing, it increases to 95 GPa for alloys with (8-9)Nb, while for 10Nb it remains at approximately 80 GPa.<\/jats:p>","DOI":"10.3390\/jfb17040179","type":"journal-article","created":{"date-parts":[[2026,4,6]],"date-time":"2026-04-06T01:12:33Z","timestamp":1775437953000},"page":"179","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Structure and Mechanical Properties of Ti-38Zr-(8-10)Nb (at. %) Alloys for Medical Use"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4018-4599","authenticated-orcid":false,"given":"Konstantin V.","family":"Sergienko","sequence":"first","affiliation":[{"name":"A.A.
