The evaluation of Ti–25Nb–8Ta–5Sn alloy prepared by 3D printing
Original language description
The most common titanium alloy used in combination with additive manufacturing is Ti- 6Al-4V ELI. On the other hand, the 3D printing of β-Ti alloys is still in the stage of development of both materials and their treatment. The newly developed biomedical Ti alloys are often containing Nb, Ta, Zr. These alloys are showing very good values in terms of biocompatibility and corrosion resistance while their elastic modulus may be in the range of 20-70 GPa. The printing of these alloys is however limited by their relative novelty. Powders are not yet available through traditional commercial ways. In this work, Ti–25Nb–8Ta–5Sn specimens prepared by the selective laser melting (SLM) method were used. The porosity was evaluated by two methods: area porosity evaluated by image analysis on metallographic specimens and volume porosity evaluated by microcomputed tomography (μCT). The microstructure was observed using both light and scanning electron microscopy (SEM). The SEM was as well used for energy dispersive spectroscopy (EDS) for chemical analysis and the analysis of crystallographic orientation was conducted using the method of electron backscattered diffraction (EBSD).
