description: The aim of this work was to investigate high-entropic alloys based on the basic composition FeNiCoCrAl2,13Mo0,5 with different ratios of basic elements and the addition of alloying elements: Nb, W, Y, Ti, Cu and Si; to determine the effect of alloying on the phase composition and hardness. Fourteen samples with different chemical compositions were prepared by induction melting. The investigated samples were subjected to homogenizing annealing at 900C. Each of the prepared samples was analysed by Thermo-Calc, X-ray diffraction analysis, energy dispersion analysis, scanning electron microscopy using Thixomet software and hardness measurements. The alloys show a multicomponent BCC solid solution, an ordered B2 BCC solid solution and a sigma phase. Increasing the share of cobalt and nickel in the basic composition leads to the disappearance of the B2C solid solution stratification and the appearance of sigma-phase. When silicon, copper and yttrium are added a large amount of sigma phase appears in the alloys. The sigma phase increases in hardness. The alloy with the highest hardness value, 903+-52 HV, was obtained with the addition of Si. The lowest hardness value is found in the base composition sample with lower Fe and Co content and low sigma phase (577+-22 HV), but this composition showed better heat resistance than the others.
