Owing to their relatively low Young's modulus, high strength, good resistance to corrosion and excellent biocompatibility, β-titanium (Ti) alloys have shown great potential for biomedical applications. In β-Ti alloys, carbon can exist in the form of titanium carbide (TiCx) as well as interstitial atoms. The Ti-C binary phase diagram predicts a minimum carbon solubility value of 0.08 wt.% in β-Ti, which has been used as the carbon limit for a variety of β-Ti alloys. However, noticeable grain boundary TiCx particles have been observed in β-Ti alloys at impurity levels of carbon well below the predicted 0.08 wt.%. This presentation will focus its attention on the trace carbon (≤ 0.08 wt.%) in biomedical β-Ti alloys containing niobium (Nb) and molybdenum (Mo), and will discuss the nature and precipitation mechanism of the TiCx particles in these alloys.
