Journal of the Mechanical Behavior of Biomedical Materials, 67, 110–116. http://doi.org/10.1016/j.jmbbm.2016.12.0051751-6161https://hdl.handle.net/10289/10837Titanium and its alloys are common biomedical materials owing to their combination of mechanical properties, corrosion resistance and biocompatibility. Powder metallurgy (PM) techniques can be used to fabricate biomaterials with tailored properties because changing the processing parameters, such as the sintering temperature, products with different level of porosity and mechanical performances can be obtained. This study addresses the production of the biomedical Ti-6Al-7Nb alloy by means of the master alloy addition variant of the PM blending elemental approach. The sintering parameters investigated guarantee that the complete diffusion of the alloying elements and the homogenization of the microstructure is achieved. The sintering of the Ti-6Al-7Nb alloy induces a total shrinkage between 7.4% and 10.7% and the level of porosity decreases from 6.2% to 4.7% with the increment of the sintering temperature. Vickers hardness (280–300 HV30) and tensile properties (different combination of strength and elongation around 900 MPa and 3%) are achieved.application/pdfenThis is an author’s accepted version of an article published in the journal: Journal of the Mechanical Behavior of Biomedical Materials. © 2016 Elsevier.Titanium alloyTi-6Al-7NbPowder metallurgyHomogeneous microstructureTensile propertiesJournal Article10.1016/j.jmbbm.2016.12.005
