The paper studies the structure and phase composition of the ceramic material obtained from the high-entropy Hf-Ti-FeV-Cr-N system with the use of the mechanical activation of the initial powder mixture with the addition of nonmetal (nitrogen) during the self-propagating high-temperature synthesis. As a result, the high-entropy ceramic (Hf0.25Ti0.25Cr0.25(FeV)0.25)N composition is obtained.
