Abstract Scope Titanium alloys display a unique set of properties, that increasingly its use in numerous application fields, ranging from aerospace structures to biomedical devices. The objective of this study was produce Ti-25Ta-Zr alloys, with the zirconium concentration varying from 0, 10, 20, 30 and 40wt%. The melting of the alloys was performed using an arc-melting furnace. The samples were characterized by x-ray diffraction using the powder method, optical and scanning electronic microscopy. The diffractograms were analysis by Rietveld’s method. X-ray measurements and Rietveld’s analysis revealed the presence of α' in the Ti-25Ta, the coexistence of α', α” and β in the Ti-25Ta-10Zr alloy; α” and β in Ti-25Ta-20Zr and Ti-25Ta-30Zr alloys, and only β in Ti-25Ta-40Zr alloy. These results were corroborated by microscopy results, with a microstructure composed by grains of β phase and needles of the α' and α” phases in the intra-grain region.
