  • The growth process of synthetic diamond single crystals under high-pressure and high-temperature (HPHT) was tested with acoustic emission technique. Associated with the fracture morphologies of the synthetic mass, the main acoustic emission dynamic parameters corresponding to growth process of diamond single crystals were analyzed. The results indicate that the energy, count, amplitude and rise time of recorded acoustic emission signals can be objective reflection of the dynamic growth process of diamond single crystals under HPHT. The research provides the important experimental basis for studying the in-situ reaction mechanics of synthetic diamond single crystals under HPHT by using acoustic emission testing.
