Abstract

The effect of the composition of a SiC–Al2O3 composite on the hardness and fracture toughness calculated by an indirect method from the total length of cracks in the corners of rhombic imprints on a Vickers hardness meter has been studied. The dependences of the hardness and fracture toughness of these composites on the content of composite components have been established.
