The directional solidification of the eutectic composition in the systems SiC-B4C, TiC-TiB2, ZrC-ZrB2 and ZrC-TiB2 was studied. Microstructure, crystallography, hardness, fracture toughness and wear were determined. In several of the studied system mechanical properties exceeded that of the end members.
