Al2O3 -TiC Composite Ceramics were prepared by hot- press sintering. The effect of the TiC content and sintering temperature was studied to investigate the mechanical property
such as density
bending strength
fracture toughness. The result indicates that TiC is very effective to improve the mechanical property
when the content of TiC is 30Vol% and the sintering temperature is 1 750℃
the value of bending strength and that of fracture toughness are the maximum
which is 5.08 MPa · m^1/2 and 620 MPa respectively. The main fracture mode of the Al2O3 - TiC composites is intracrystalline fracture
