    Abstract

    A new beta titanium alloy, Ti-12Mo-6Zr-2Fe (TMZF) was developed for orthopaedic use. This alloy has a desirable combination of properties, i.e. low modulus of elasticity, excellent mechanical strength, corrosion resistance, and formability, coupled with good wear and notch fatigue resistance. Also, no vanadium and aluminum in this alloy offer a biocompatibility advantage over the Ti-6Al-4V alloy. The processing development, metallurgical characteristics, physical and mechanical properties, and wear resistance of this new alloy are reported here.
