Microstresses in Thermally Stable Diamond Composites made by High Pressure Infiltration Technique

Microstresses in the diamond and SiC phases of the TSDCs (thermally stable diamond composites), produced by the high pressure infiltration technique, were measured using the neutron diffractometer, KOWARI, at the OPAL research reactor. Microstresses are developed as a result of the cooling and pressure reduction from the sintering high temperature and high pressure (HTHP) conditions. Their magnitude is determined by the thermo-mechanical properties of the SiC matrix and diamond grit, pressure and temperature conditions as well as the exact TSDC phase composition. The experimental results were interpreted in terms the “matrix-inclusion” composite model that was used to evaluate the composite structural integrity.
