Abstract
This invention describes a biocompatible, radiopaque, high-strength, low-modulus, titanium based alloy having about 2-30 weight percent Mo and up to about 30 weight percent Hf. This alloy is suitable for use in the fabrication of medical implants and devices having low modulus, improved corrosion resistance and surface hardening. To increase strength, Cr, Si and Fe can be added in small amounts as well as increasing levels of interstitial oxygen, nitrogen or carbon. To maintain low elastic modulus, Mo can be partially substituted by Nb.
