Abstract
In recent years, different beta titanium alloys have been developed for biomedical applications with a combination of mechanical properties including a low Young's modulus, high strength, fatigue resistance and good ductility with excellent corrosion resistance. From this perspective, a new metastable beta titanium Ti–12Mo–3Nb alloy was developed with the replacement of both vanadium and aluminum from the traditional Ti–6Al–4V alloy. This paper presents the microstructure, mechanical properties and corrosion resistance of the Ti–12Mo–3Nb alloy heat-treated at 950°C for 1h. The material was characterized by X-ray diffraction and by scanning electron microscopy. Tensile tests were carried out at room temperature. Corrosion tests were performed using Ringer's solution at 25°C. The results showed that this alloy could potentially be used for biomedical purposes due to its good mechanical properties and spontaneous passivation.
