“…For example, Ti-Nb-Fe-Sn, Ti-Nb-Fe-Zr, and Ti-Nb-Fe-Cr alloys are developed as low-cost biomedical Ti alloys. [43][44][45][46] However, Young's modulus of these alloys is still higher than 50 GPa. In this study, Ti-Nb-Fe-Sn alloys with relatively low Nb content were designed and optimized to achieve low Young's modulus comparable to human bone.…”

Ti–Nb–Fe–Sn alloys with relatively low Nb content, located near the phase boundary of (β + ω)/β, are designed on the basis of electron‐to‐atom (e/a) ratio, d‐electron alloy design concept, and Mo equivalent (Moeq) aiming at low Young's modulus comparable to human bone. The effect of Sn content and Nb content on the microstructure and the mechanical properties is investigated in Ti–5Nb–3Fe–(0–6)Sn (at%) and Ti–(3–9)Nb–3Fe–4Sn (at%) alloys. The composition dependence of Young's modulus and tensile strength of Ti–Nb–Fe–Sn alloys is analyzed in terms of the phase stability, ω phase, and recrystallization texture. Both Nb and Sn are effective in suppressing the athermal ω phase and stabilizing the β phase. The recrystallization texture is strongly influenced by the content of Sn and Nb. A strong {110}β<001>β Goss texture is formed in the Ti–5Nb–3Fe–(2–4)Sn and Ti–(3–5)Nb–3Fe–4Sn alloys. The Ti–5Nb–3Fe–4Sn alloy exhibits an exceptionally low Young's modulus of 30 GPa due to the combined effects of low stability of the β phase, a small amount of ω phase, and a strong Goss texture.
