摘要

Titanium and its alloys have been used as most attractive bio-compatible metallic materials due to their excellent combination of strength, corrosion resistance and bio-compatibility,β-type titanium alloy, Ti-29Nb-13Ta-4.6Zr, which composed of non-toxic elements with low modulus of elasticity is newly developed for biomedical applications. Forging, cold rolling and heat treatments were conducted with Ti-29Nb-13Ta-4.6Zr in order to achieve excellent mechanical performance. The tensile tests, fatigue tests, measurements of modulus of elasticity and evaluation of cyto-toxicity were carried out in order to investigate the basic mechanical and biological properties of Ti-29Nb-13Ta-4.6Zr. The balance of strength and ductility, and fatigue ratio of Ti-29Nb-13Ta-4.6Zr are equivalent or greater, and the modulus of elasticity and cyto-toxicity of Ti-29Nb-13Ta-4.6Zr are equivalent or lower comparing with those of conventional biomedical titanium alloys. Newly developed β-type titanium alloy, Ti-29Nb-13Ta-4.6Zr, is, therefore, judged to be suitable for biomedical applications.
