Physico-mechanical and physicochemical interaction at sintering of cBN-TiB₂ composites under ultrahigh pressure
It has been shown in experiment that at the reactive sintering of cubic boron nitride with aluminum under high pressures and temperatures, addition of TiB₂ results in shifting of the reaction towards crystallization of aluminum diboride instead of higher diborides and provides the absence of residua...

The calculated values of residual thermal stresses in cBN and TiB₂ phases sintered under 8GPa at 2300 K are considerably lower than the phase flexural strength.
