TiB_2–44%TiC(in mole fraction) composite ceramics with an eutectic composition were prepared by hot pressing sintering with TiB_2–TiC composite powders synthesized by direct and indirect carbon–boron thermal reduction processes, respectively. The effects of the synthesis process and sintering temperature on the microstructure and mechanical properties of TiB_2–TiC composite ceramics were investigated. The results show that TiB_2 grains in TiB_2–TiC composite ceramic sintered with TiB_2–TiC composite powder ...
