Physico-mechanical properties of cBN composites produced by a high-pressure reaction sintering of cubic boron nitride and aluminum owders

Physico-mechanical properties (fracture toughness, hardness and its dependence on the temperature) have been considered of samples of composites of the cBN-Al system produced at a pressure of 4.2 GPa and temperature of 1750 K with the variable aluminum content of the reaction mixture and time of sin...

Summary:Physico-mechanical properties (fracture toughness, hardness and its dependence on the temperature) have been considered of samples of composites of the cBN-Al system produced at a pressure of 4.2 GPa and temperature of 1750 K with the variable aluminum content of the reaction mixture and time of sintering. The effect of the phase composition and real crystalline structure on the composite properties has been shown.
