Abstract

The increased interaction time between the implant and the human body has led to the search for new materials used in the manufacture of implants. In this way, β-Ti alloys free of toxic elements have gained prominence, such as Ti-40Nb. In this work, an alloy ingot was swaged and bars with 10, 8 and 7 mm diameter were obtained. All conditions, including as-cast, had their microstructure characterized by x-ray diffraction, optical microscopy, scanning electron microscopy and transmission electron microscopy (TEM). Mechanical and physical properties were evaluated by Vickers microhardness and elastic modulus measurements. The results showed that the swaging process reduced the Vickers hardness and elastic modulus, respectively, by 31 and 19% for the Ti-40Nb alloy, around 187 HV and 61 GPa (SW8). In addition, using the TEM technique, phase separation (spinodal decomposition) was detected, as well as stress-induced omega, both at the nanoscale.
