TiC toughened with Nb and Mo were investigated with regards to their fracture toughness, focusing on microstructural change. Microstructure was observed in a scanning electron microscope (SEM) and a transmission electron microscope (TEM). Phase identification and chemical analysis were performed by a X-ray diffractometer and an electron probe microanalyzer. Fracture toughness of the annealed TiC composites was found to be higher than that of the monolithic TiC and the as-cast ones, which increases with increasing Nb content.
