description: The given work is devoted to the production and study of highly entropic CrNbMoVW based on refractory elements. The research set the following goals: 1. Analysis of the conditions of formation of a solid solution in a multicomponent system CrNbMoVW 2. Synthesis of powder material by mechanical alloying. Subsequent compacting of the material using a spark plasma sintering plant 3. The study of the microstructure and phase composition of the samples 4. The study of mechanical (compressive strength, wear resistance, hardness), corrosion properties of the material 5. The study of the influence of sintering temperature on the final properties of samples. The work was carried out on the basis of the laboratory âDesign of materials and additive manufacturingâ, where a significant part of the work was carried out: carrying out experiments on synthesis, analysis of the microstructure and phase composition, analysis of mechanical and corrosion properties. The conditions for the formation of a single-phase solid solution for the CrNbMoVW system are calculated. As a result of the work, the highly entropic CrNbMoVW alloy was synthesized and the properties of the material on compact samples were investigated. The results of the study showed that a highly entropic alloy has high wear-resistant and corrosive properties. A computer model was constructed that estimates the possibility of the formation of a single-phase solid solution in a multicomponent system based on thermodynamic parameters.
