Spark plasma sintering (SPS method) method was used to densify Ti-x wt.% Si compounds materials from Ti and Si powders. Sintered Ti and Ti-x wt.%) Si materials were almost entirely dense with a relative density of up to 100% after applying an electric current for 11 min under 60 MPa of pressure at 1000 oC. The average grain size of Ti5Si3 compound obtained from Ti-10 wt.% Si powder was of about 35 nm with a hardness of ~ 640 kg/mm2.
