This paper reports dispersed-phase composites of TiC-Al{sub 2}O{sub 3} fabricated from low-cost reactants by external ignition of powder compacts followed by dynamic consolidation of the hot products using explosives. Near full densification was achieved using shock pressures as low as 1 GPa. Care must be taken to allow for the escape of evolved gases during exothermic reaction, and rapid cooling of the consolidated composite must be avoided to prevent cracking.
