Dense TiB₂-TiC_xN_1-x and TiB₂-Ti(C_0.5N_0.5)_y composites were synthesized from powder mixtures of B₄C, BN and Ti by reactive spark plasma sintering. The reaction 2_xB₄C+2(1-x)BN+3(x+1)Ti→(3x+1)TiB₂+2TiC_xN_1-x for TiB₂-TiC_xN_1-x and the reaction B₄C+BN+(5/2+2/y)Ti→5/2TiB₂+2/yTi(C_0.5N_0.5)_y for TiB2-Ti(C0.5N0.5)y, proceeded during their sintering. The relative density of the TiB₂-TiC_xN_1-x composites increased as the nitrogen content decreased, and the composites had relative densities more than 99 % at higher x than 0.5. The Young's modulus, Vickers hardness and fracture toughness of the composites increased with increasing x. For TiB₂-Ti(C_0.5N_0.5)_y composites, the relative density became still higher than 99.1 % at smaller y than 1, i.e., increasing nonstoichiometry. However, the Young's modulus, Vickers hardness and fracture toughness decreased with decreasing y value.
