A method of the reaction hot pressing was used to produce composites from the B₄C–(5–15%)(TiH₂–VC) system, established the peculiarities of their structures and measured physico-mechanical parameters. The dense dispersion-hardened materials having a high bending strength (R_bm = 420–580 MPa) and increased fracture toughness (K_Ic = 4.1–4.8 MPa·m^1/2) on retention of the HKN = 19–20 GPa are promising for the use in the conditions of the severe abrasive wear.
