Abstract

A review of bioinert titanium alloys based on metastable β-solid solution, which can be used as orthopedic implants is presented. The effect of β-stabilizers and neutral hardeners (Zr, Sn) on the properties (elastic modulus, strength, plasticity) of Ti – Nb alloys is considered. Experimental and computational data are used to show that in order to obtain a reduced elastic modulus (up to 50 – 55 GPa) in quenched condition, the Ti – Nb binary system should be alloyed additionally with Zr and/or Sn. Such alloying provides additional strengthening of the Ti – Nb alloys to up to σ_0.2 = 450 – 650 MPa at an elongation of 10 – 40%.

生物惰性钛合金的合金化及其性能研究进展

本文综述了基于亚稳β-固溶体的生物惰性钛合金用于骨科植入物的研究进展。研究了β稳定剂和中性固化剂（Zr、Sn）对Ti - Nb合金弹性模量、强度、塑性等性能的影响。实验和计算结果表明，为了使Ti - Nb二元体系在淬火条件下获得较低的弹性模量（可达50 ~ 55 GPa），必须在Ti - Nb二元体系中添加Zr和/或Sn。这种合金使Ti - Nb合金的强度达到σ0.2 = 450 - 650 MPa，伸长率为10 - 40%。
