1. Ultrafine-Grained Ti-13Nb-13Zr Alloy Produced by Severe Plastic Deformation
Biomedical devices currently in use (prostheses, implants) have satisfactory performance in many cases. However, sometimes the body reacts to the device insertion and may lead to its rapid replacement. Some of these disadvantages can be solved by the use of titanium and its alloys, due to their excellent combination of corrosion resistance, wear resistance a

2. Dynamical Elastic Moduli of the Ti-13Nb-13Zr biomaterial alloy by mechanical spectroscopy
Dynamical Elastic Moduli of the Ti-13Nb-13Zr biomaterial alloy were obtained using the mechanical spectroscopy technique. The sample with heat treatment at 1170K for 30 minutes and water quenched with subsequent aging treatment at 670 K for 3 hours (TNZ + WQ + 670 K/3 h), was characterized through decay of free oscillations of the sample in the flexural vibr

3. Caracterização do módulo elástico por espectroscopia mecânica da liga Ti-13Nb-13Zr
In the present time the titanium and their alloys are begin widely studied in the field of biomaterials because of its suitable mechanical properties such as low elastic modulus, excellent corrosion resistance and high biocompatibility. Recent studies are being focused on alloys free of toxic elements as Al and V, which are contained in the alloy Ti-6Al-4V t

5. The effect of polarisation on the electrochemical behavior of Ti-13Nb-13Zr alloy
The effect of potentiostatic polarisation on the electrochemical behavior of the Ti-13Nb-13Zr alloy was investigated by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarisation curves in Hanks' solution at 37 °C. Potentiodynamic polarisation curves show a passive behavior with a slight current increase as potentials around 1300 mV(SCE).

6. The effect of hydrogen peroxide on the electrochemical behaviour of Ti-13Nb-13Zr alloy in Hanks' solution
Titanium alloys are largely used for biomedical applications mainly due to their high corrosion resistance resulting from the protective oxide film formed on their surface. The literature, however, has pointed out discrepancies between in vitro tests and in vivo tests. These discrepancies have been ascribed to hydrogen peroxide (H2O2) generated by inflammato
