Shock compaction experiments for some diamond composites were carried out, and the best consolidated compacts of diamond/SiC and diamond/TiC had relative densities of 95% and 96%, and microhardnesses of 51 ± 2.9 and 48.6 ± 4.8 GPa, respectively. For obtaining better compacts on the shock compaction of mixtures, the ratio of the constituent particle sizes and the properties of the constituent materials are considered, and then the starting conditions of the mixtures must be decided. Here, a simple model concerned with the influence of both the ratio of the constituent particle sizes and the thermal properties of the constituent materials on the shock compaction of mixtures is also presented.
