Conclusions

  1. 1.

    An investigation was carried out into the variation of some properties of (TiC-MeC)-NiMo alloys, where Me is vanadium, niobium, or tantalum, with their MeC content (2–25 mole % in the binary carbide). The following properties were studied: transverse rupture and compressive strengths, hardness, impact strength, modulus of elasticity, coefficient of thermal expansion, oxidation resistance, antifriction characteristics exhibited during rubbing against chromium cast iron, and internal friction background.

  2. 2.

    It is shown that the addition to the hard phase of up to 5 mole % VC and 5–15 mole % NbC or TaC has a beneficial effect on many properties of these alloys, which is a result of a slight increase in the ductility of their carbide grains.

  3. 3.

    The alloys are potentially useful as materials for metalworking tools and as high-temperature constructional materials.
