High‐Pressure Self‐Combustion Sintering of Titanium Carbide

Abstract

A high‐pressure self‐combusiton sintering process has been applied to the synthesis and simultaneous sintering of titanium carbide. A dense titanium carbide compact was easily fabricated from the constituent elements without sintering aids under 3 GPa. The compact was composed of well‐crystallized grains with a mean diameter of 20 μm at a molar ratio of C/Ti =0.95. The maximum values of the relative density and the Vickers microhardness were 96.5% and 31 GN/m 2 , respectively, at room temperature.
