| Abstract Scope |
Ti–Nb–Fe–Sn shape memory alloys with relatively low Nb content, located near the phase boundary of (β þ 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 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 ω phase, and recrystallization texture. The recrystallization texture is strongly influenced by the content of Sn and Nb. A strong {110}β<001>β Goss texture isformed in the Ti–5Nb–3Fe–(2–4)Sn 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. |
