  • Publication number: 20140112820
    Abstract: A beta-based titanium alloy with a low elastic modulus includes 37 wt. % to 41 wt. % niobium (Nb), 5 wt. % to 8 wt. % zirconium (Zr), and a balance of titanium (Ti), with unavoidable impurities, and having an elastic modulus of 47 GPa or lower. The beta-based titanium alloy has a much lower elastic modulus than the typical biomedical titanium alloys, and thus can resolve the problem of so-called “stress shield effect.” Therefore, the beta-based titanium alloy can be widely used as a material for general civilian goods such as eyewear frames and headsets and sports and leisure goods, as well as a biomedical material for artificial bones, artificial teeth and artificial hip joints.
