The V-Al-N-C alloy was obtained by the method of out-of-furnace aluminothermic smelting of a mixture containing vanadium pentoxide, aluminum powder, nitrided by the SHS method powdered V-Al-(17-20)N (wt.%) alloy and graphite in copper uncooled molds. The phase composition was determined by X-ray phase analysis (diffractometer - DRON-2.0, radiation - Cu-Kα, monochromator - graphite). The microstructure and composition of the phases were investigated by X-ray microanalysis using a JSM-59000LV scanning electron microscope ( Japan) and an Oxford INCA Energy 200 energy-dispersive X-ray spectrometer (United Kingdom). It is revealed that the matrix of the V-Al-N-C alloy, containing (wt. %): 73.9 V; 23.7 Al, 1.2 N, 0.69 C, and 0.08 O<span class="s1">2</span>, are represented by the solid solution of aluminum in vanadium. The main nitrogen-containing phase is aluminum nitride AlN of a cubic structure. The carbide phase can be identified as V<span class="s1">2</span>Al<span class="s1">0.9</span>C<span class="s1">1.1</span&gt;. Nitride and carbide phases are distributed quite uniformly in the alloy matrix. The carbide phase in the structure of the V-Al-N-C alloy is predominantly in the form of threadlike crystals up to 100 μm in length. The nitride phase is represented by small (up to 10 μm) and large (30 ÷ 100 }, number={1}, journal={KnE Materials Science}, author={D V, Taranov and A V, Larionov and V M, Chumarev and L A, Smirnov and M V, Trubachev and S A, Vohmentsev}, year={2019}, month={Mar.}, pages={118–125} }
