| Abstract: | The critical stress intensity factor and other related fracture parameters have been measured in three-point bending for pure Al2O3-TiC composites containing 4 to 35 volume fractions of TiC. An increase has been observed for all the parameters with increasing volume fraction of TiC. Following a study of the mode of fracture, the results are explained in terms of a linear variation of the fracture energy with the volume fraction of TiC. |
