| Abstract |
| Flexural Strength, fracture toughness and microstructure
of sintered silicon carbide doped with boron carbide prepared
by pressureless sintering route from nano-crystalline
silicon carbide particles (prepared by attrition grinding from
an Acheson type a-SiC) were studied. The strength of the
materials was characterized in terms of baseline strength,
strength distribution and microstructure. The average
flexural strength was found to be 390 MPa and average
fracture toughness was 3.95 MPa.m112• |
