A study was carried out to establish changes in mechanical properties: hardness and microhardness depending on the content of the chemical composition of high-entropy alloys of the CoCrFeMnNi system. Scanning electron microscopy methods were used to study the microstructure, chemical composition of non-metallic inclusions and elemental mapping. The size of non-metallic inclusions was 8 µm with the release of oxide compounds Mn2O3. Microstructural analysis using energy dispersive spectrometry was carried out pointwise in the dendritic region and established an increased content of elements such as Co, Cr, Fe with a high melting point, as well as the release of low-melting materials Ni and Mn in the interdendritic layers.
