High specific strength of Ti-based alloys makes them desirable materials for various structural applications including anti-ballistic protection. Essential anti-ballistic properties of materials can be attained by formation of the gradient microstructures that combines high strength at the surface of the alloy parts with sufficient toughness in their core. Our present study reports results on layered structures of Ti-based alloys fabrication by means of Blended Elemental Powder Metallurgy (BEPM) using hydrogenated titanium and alloying elements powders. Combined multi-layered structures of CP Ti, Ti-6Al-4V, Ti-1Al-8V-5Fe (wt.%) alloys, some strengthened with inclusions of fine TiB2 and TiC particles were sintered. Further heat or thermomechanical treatment was used to modify alloys’ microstructure and porosity to optimize their mechanical properties.
