The melting temperature, microstructure, and phase composition of cast eutectic alloys with niobium carbide, in which the metal base represented by nickel or nickel and cobalt, are studied by methods of physicochemical analysis. The properties of the studied alloys are comparable with the corresponding properties of the industrial eutectic composite based on cobalt with niobium carbide. The melting point of the eutectic (solidus) of nickel-based alloys is above 1300°C and does not differ from the corresponding value for cobalt serial alloy. The structure of alloys has slightly over-eutectic features and is determined by the presence of primary undeveloped niobium carbide dendrites in the eutectic of dispersed eutectic carbide crystals in an alloyed metal base. In the phase composition of the studied alloys, along with a solid solution of alloying elements in Nickel ($\gamma$) and niobium carbide (NbC), there are metastable phases enriched in chromium and rhenium. According to the complex of structural properties, cast eutectic alloys of nickel with niobium carbide are promising for use as an alternative to cobalt alloys of the ХТН series.

Key words: cobalt, nickel, niobium carbide, eutectic, melting point, structure, phase composition.
