Abstrakt: 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 (Rbm = 420-580 MPa) and increased fracture toughness (KIc = 4.1-4.8 MPa·m1/2) on retention of the HKN = 19-20 GPa are promising for the use in the conditions of the severe abrasive wear.
