A ternary eutectic composite B4C–8TaB2–40SiC (mol %) is prepared using the method of directional crystallization. The properties of the obtained material are investigated, and the following facts are established: the material has a fine-grained homogeneous structure of the B4C–TaB2–SiC ternary eutectic system of the lamellar type throughout the sample volume, the Vickers hardness value is 33–34 GPa, and the fracture toughness is 3.9 MPa m1/2. The thermal expansion coefficient of the composite is investigated in the temperature range of 22–1600°C. [ABSTRACT FROM AUTHOR] |
