Preliminary results are presented on the work on combining the Self-sustained High-temperature Synthesis (SHS) of ceramics with Dynamic Compaction (DC) using the indirect cylindrical configuration. A gap between flyer-tube and SHS-tube provides the necessary thermal isolation for the explosive layer surrounding the flyer-tube. Temperature measurements on the flyer-tube have been performed during the SHS of TiC from a Ti/C powder mixture. This provided the maximal time delay for the SHS/DC experiments to be applied between the SHS and DC processes, before the explosive attains too high a temperature. The first samples of TiC after SHS/DC still show cracks, but have a hardness of 24 GPa, comparable with dense sintered TiC samples.
