TY - JOUR AU - Ivakhnenko, S. AB - Mechanical properties of a type IIb synthetic diamond produced by the temperature gradient method have been studied at 900°C using indenters having different angles between the pyramid axis and face. The strain-strain curve has been constructed in the stress-total strain coordinates. It has been shown that in the diamond deformation the strain hardening with a linear dependence of flow stress on the plastic strain degree occurs. It has been found that the microhardness and fracture toughness of the tested synthetic diamond and natural diamond and the mechanism of their deformation do not differ essentially.
