Summary

Dense compacts of Ti and C elemental powder mixtures (88% TMD of Ti+C mixture) were prepared by shock compaction using a cylindrical implosion setup. Triangular sections of the shocked compacts were machined and reaction-sintered in an induction-heated hot press at temperatures below the melting point of Ti, with constant hold time of 60 minutes. TiCx compacts, with bulk density in the range of 3.94-4.04 g/cm3 (80-82% TMD of TiC) and highly refined microstructures, were produced. In this paper, reaction sintering mechanisms involving solid-state diffusion in Ti+C powder mixture compacts will be described, along with characteristics of the titanium carbide produced by the combined shock-modification and reaction sintering approach.
