Self-propagating high-temperature synthesis of high-entropy ceramic composition (Hf0.25Ti0.25Cr0.25(FeV)0.25)N

•The high-entropy ceramic (Hf0.25Ti0.25Cr0.25(FeV)0.25)N composition was obtained.•The SHS products possess the FCC crystal structure.•System elements distribute throughout the surface of the synthesized specimen.•Shown the possibility to synthesize HEC from the Hf-Ti-FeV-Cr-N system using the SHS. 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.
