Room temperature uniaxial and flexural strength, Weibull parameters, and fracture toughness of hot pressed TiB{sub 2} are presented. Fracture toughness estimated from fractographic analysis was compared to the SEPB K{sub IC} measurements. Discrepancy between the estimated and measured values were rationalized by invoking the possibility of R-curve behavior. Fractographic analysis and the load displacement records of Vickers indented specimens point to the existence of rising R-curve behavior.
