The titanium is on excellent material for fabrication of aerospace springs in substituting to steels, due to its high corrosion resistance, 60% lower density, and lower elastic modulus. The production of the titanium alloys by powder metallurgy (M/P), starting from the elemental powders is a feasible route considering its lower costs and versatility. In this work, results of the Ti-3Al-8V-6Cr-4Mo-4Zr (β-C) and Ti-35Nb-7Zr-5Ta alloys production are presented. Samples were cold isostatic pressing (350 MPa) with subsequent densification by sintering at 1200, 1400 and 1500 °C, in vacuum. Sintered samples were characterized for phase composition, microstructure and microhardness by X-ray diffraction, scanning electron microscopy and Vickers indentation, respectively. Density was measured by Archimedes method. It was shown that the samples were sintered to high densities and presented homogeneous microstructure.
