Abstract

B4C based ceramics composites with 0–25 mol% CrB2 were fabricated by pressureless sintering in the temperature range 1850°C to 2030°C. The CrB2 addition enhanced the densification of B4C due to the CrB2–B4C eutectic liquid phase formation. Both a high strength of 525 MPa and a modest fracture toughness of 3.7 MPa m1/2 were obtained for the B4C–20 mol% CrB2 composite with a high-relative density of 98.1% after sintering at 2030°C. The improvement in fracture toughness is thought to result from the formation of microcracks and the deflection of propagating cracks resulting from the thermal expansion mismatch of CrB2 and B4C.
