A graded dispersion of diamond in TiB2/Si cermet (90vol% diamond layer / diamond graded dispersed layers / matrix) was achieved by dynamic pseudo isostatic compaction (DPIC) just after self-propagating high temperature synthesis (SHS). The DPIC was performed using commercial casting sand as the pressure transmitting medium for the densification of the cermet. The process enabled to simultaneously synthesize and densify the cermet matrix within a few minutes. Diamond (an average particle size, approximately 30μm) mixed with the reactant was fixed in the matrix produced after the SHS. The maximum combustion temperatures were controlled to be approximately 2000 K to prevent the diamond to graphite transformation. The diamond particles were found to be strongly fixed in the matrix even after lapping with a diamond abrasive by SEM. A simple calculation of residual stress based on the graded volume ratio of diamond in the matrix was also performed.
