“…Figure 2 shows micrographs of (a, b) Ti-10Mo-3Nb (SEM), (c, d) Ti-10Mo-6Nb (SEM) and (e, f) Ti-10Mo-9Nb (SEM and OM, respectively) alloys. The adopted heat-treatment could not completely eliminate the as-cast dendrite structures observed in previous studies 17 . This was more visible in the alloy with lower Nb content and is a consequence of the relatively low temperature (950 °C) of heat treatment.…”

This study has investigated the niobium (Nb) additions effect on both microstructure and heat-treated Ti-10Mo-xNb (x = 3, 6 and 9) alloys mechanical properties. The microstructures were characterized by optical microscopy, X-ray diffraction and transmission electron microscopy. The mechanical characterization was carried out by Vickers microhardness test and Young's modulus measurements. The outcomes show that the addition of Nb in alloys decreased the proportion of ω and α' phases. The Ti-10Mo-3Nb alloy presented the best hardness and elastic modulus combination among the three developed alloys and also with respect to Ti-6Al-4V alloy and commercially pure Ti.

“…Gabriel et al studied a series of Ti–10Mo– x Nb alloys ( x = 3, 6, 9, 20, and 30 Wt % of niobium) in regards to their microstructural characterization, stabilization of β phase, and mechanical properties, including microhardness and elastic modulus. It was also verified that at levels above 3 Wt % of niobium, a matrix with only a β phase was observed.…”

In the development of new metallic biomaterials, the Ti-15Mo alloy has great prominence because of its excellent corrosion resistance and good combination of mechanical properties. In this study, the element niobium was added to the Ti-15Mo alloy, forming the Ti-15Mo-Nb system for the purpose of improving their properties and promoting its application as a biomaterial. These alloys are very promising to use as biomedical implants, because they integrate a new class of titanium alloys without the presence of aluminum and vanadium, which may cause cytotoxic effects. The alloys were produced by arc-melting and characterized by density, X-ray diffraction, scanning electron microscopy, microhardness, elastic modulus, corrosion, and cytotoxicity assays. The developed alloys have β phase predominance (with bcc crystalline structure). The addition of niobium decreases the microhardness and elastic modulus, with values around 80 GPa, which is well below that of the metallic alloys used commercially for this type of application. Very low passive current densities were found for all alloys studied showing that the passive film on these alloys is highly protective. In vitro cytotoxicity tests revealed that the introduction of niobium did not cause cytotoxic effects in the studied alloys. © 2017 Wiley Periodicals, Inc.

Beta titanium alloys were developed for biomedical applications due to the combination of its mechanical properties including low elasticity modulus, high strength, fatigue resistance, good ductility and with excellent corrosion resistance. With this perspective a metastable beta titanium alloy Ti-12Mo-13Nb was developed with the replacement of both vanadium and aluminum from the traditional alloy Ti-6Al-4V. This paper presents the microstructure, mechanical properties of the Ti12Mo-13Nb hot swaged and aged at 500 o C for 24 h under high vacuum and then water quenched. The alloy structure was characterized by X-ray diffraction and transmission electron microscopy. Tensile tests were carried out at room temperature. The results show a microstructure consisting of a fine dispersed α phase in a β matrix and good mechanical properties including low elastic modulus. The results indicate that Ti-12Mo-13Nb alloy can be a promising alternative for biomedical application.
