The present work demonstrates the feasibility of preparing bulk-Ti, with high strength and good ductility, via spark plasma sintering of TiH2 powders. The microstructure and mechanical properties of bulk titanium prepared under two different processing conditions, i.e. (i) Simultaneous dehydrogenation and sintering under one-step spark plasma sintering (SPS), and (ii) dehydrogenation in vacuum followed by Spark Plasma Sintering i.e. two-step SPS, are presented and discussed. The one-step sintering process, i.e. process (i), resulted in Ti specimens with very high tensile strength, but poor ductility. On the other hand, two-step sintering process, i.e. process (ii), resulted in bulk Ti with high strength and high ductility.
