“…Figure 1a shows the X ray diffraction pattern of the sample TNZ + WQ + 670 K/3 h, where can be observed the presence of α and β phases with structure hcp and bcc respectively, which are in agreement with the observed in the literature 2,5,7 for this titanium alloy when submitted to aging treatment.…”

“…Thus, among the new research of alloys for biomedical applications based in titanium free of toxic elements and with appropriate mechanical properties and high biocompatibility the Ti-13Nb-13Zr (TNZ) alloy appears as an option to be taken into account because the processing variables can be controlled to lead selected results 4 . Ti-13Nb-13Zr alloy is typically an near-β Ti alloy which, when heat treated up the β-transus temperature and water-quenched posses a hexagonal α´-phase martensite microstructure, but followed by an aging treatment that is transformed into a martensite formed by α-phase (hcp structure) with precipitates of β−phase (bcc structure) [5][6][7] . In general it is of great interest to know in a metallic alloy the behavior of alloying elements and the mechanical properties, specifically the elastic modulus in biomaterials, therefore the mechanical spectroscopy becomes an important tool for characterization because it can provide information about the interaction of the matrix with the solutes atoms (substitutional and interstitial) [8][9][10][11] , besides dynamical elastic modulus (elastic modulus as function of temperature) 12 parameter of great importance from the viewpoint of biocompatibility.…”

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 vibration mode. The spectra of anelastic relaxation (internal friction and frequency) in the temperature range from 300 K to 625 K not revealed the presence of relaxation process. As shown in the literature, the hcp structure usually does not exhibit any relaxation due to the symmetry of the sites in the crystalline lattice, but if there is some relaxation, this only occurs in special cases such as low concentration of zirconium or saturation of the stoichiometric ratio of oxygen for zirconium. Dynamical elastic modulus obtained for TNZ + WQ + 670 K/3 h alloy was 87 GPa at room temperature, which is higher than the value for Ti-13Nb-13Zr alloy (64 GPa) of the literature. This increment may be related to the change of the proportion of α and β phases. Besides that, the presence of precipitates in the alloy after aging treatment hardens the material and reduces its ductility.

Development of submicrocrystalline structure in biomedical alloy such as Ti-13Nb-13Zr (in wt%) through warm-rolling process has been found to enhance mechanical properties compared to conventional thermomechanical processing routes including hot-rolling process. The present study investigated the tribological and corrosion behaviors of warm-rolled (WR) and hot-rolled Ti-13Nb-13Zr alloys which have not been studied to date. Both tribological and corrosion experiments were carried out in simulated body fluid conditions (Hank’s solution at 37°C) based on the fact that the investigated alloys would be used in a human body as orthopedic implants. The WR Ti-13Nb-13Zr demonstrated a submicrocrystalline structure that provided a significant enhancement in hardness, strength, and corrosion resistance. Meanwhile, there was no notable difference in wear resistance between the WR and hot-rolled samples despite the different microstructure and hardness. The present study confirmed the enormous potential of WR Ti-13Nb-13Zr with not only great mechanical properties but also high corrosion resistance in the simulated body fluid.
