Titanium alloys parts are ideally suited for advanced aerospace systems, chemical and naval applications and surgical implants because of its high strength-to-weight ratio, high resistance to many corrosive environments, and can be used over a wide range of temperatures. Powder metallurgy of titanium and Ti-based alloys may lead to the obtainment of components having weak-to-absent textures, uniform grain structure and higher homogeneity compared with conventional wrought products. In this work, results of the densification of Ti-6Al-4V, Ti-6Al-7Nb and Ti-13Nb-13Zr alloys after cold and isostatic pressing with subsequent densification by sintering between 900-1400°C using hydride titanium powders are presented. The samples were characterized by X-ray diffraction, scanning electron microscopy, Vickers indentation and density measurements.
