Abstract
This invention describes a corrosion-resistant, high-strength, low-modulus, titanium based alloy having about 5-11 weight percent Mo and about 6-15 weight percent Hf. This alloy is suitable for use in the fabrication of articles for medical and non-medical applications 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.
