Accurate quantitative EDS-TEM analysis of precipitates and matrix in equilibrium (α+β) Zr–1Nb alloys with Ta addition
(Elsevier Science SA, 2020-12)
The (α+β) phase microstructure in Zr-1.05Nb, Zr-0.85Nb-0.20Ta and Zr-0.85Nb-0.40Ta (wt.%) alloys annealed at 570 °C for 3840 h after β-quenching were observed at different scales by optical, SEM and TEM microscopies. A ...
Diffusion calculations with two atomic models in h.c.p Zr-Nb diluted alloys
(Elsevier Science Sa, 2017-08)
In this work we perform a comparison of atomic diffusion multi-frequency models for h.c.p. lattices. Specifically, in diluted h.c.p. αZr-Nb alloy, we calculate, the tracer self- and impurity diffusion coefficients, with ...
Effects of thermo-mechanical process on phase transitions, hydrogen solubility and corrosion of Ta-modified Zr-1Nb alloys
(Elsevier, 2021-09)
The feasibility of using Ta as a minor alloying element in Zr-1Nb alloys is addressed in terms of phase stability and resistance to corrosion of the microstructure obtained with the following two thermomechanical processes ...
Dynamical Elastic Moduli of the Ti-13Nb-13Zr biomaterial alloy by mechanical spectroscopy
(ABM, ABC, ABPol, 2012-12-01)
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 ...

Influence of surface treatments on corrosion resistance properties of ultrafine grained titanium alloys for biomedical applications
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2019-08-09)
Titanium and its alloys are used as biomaterials because their excellent combination of high corrosion resistance, low modulus of elasticity and biocompatibility. However, titanium and its alloys cannot meet all the clinical ...
Caracterização mecânica, física e química das ligas Ti-35Nb-5Zr e Ti-35Nb-10Zr
(Universidade Estadual Paulista (UNESP), 2014)
Structure, microstructure, and selected mechanical properties of Ti-Zr-Mo alloys for biomedical applications
(2014)
New titanium alloys for biomedical applications have been developed primarily with the addition of Nb, Ta, Mo, and Zr, because those elements stabilize the β phase and they don’t cause cytotoxicity in the organism. The ...
