description: The object of the study was samples of high-entropy alloys of the Fe-Ni-Co-Cr system with the addition of Mo, Al, Ti. The research set the following goals: 1) Study of the influence of Mo, Al, Ti on the phase composition in the Fe-Ni-Co-Cr system. 2) Analysis the effect of heat treatment on the structure of the best alloys. 3) Get the powder of the selected composition and investigate the microstructure. Using data from scientific literature, the compositions of alloys based on the single-phase system Fe-Ni-Co-Cr with the addition of Mo, Al, Tiwere selected and obtained in an induction furnace. The influence of alloying elements has been studied using a scanning electron microscope, an X-ray diffractometer, a microhardness tester, and thermodynamic calculations performed in the Thermo-Calc program. Based on the data obtained on structure formation in the studied high-entropy alloys, a series of Fe-Ni-Co-Cr-Mo12-Alx samples with an Al concentration of 4 to 29 atomic percent was obtained. Differences in the structure and in the values of microhardness were investigated in the obtained compositions. After the performed heat treatment for the compositions (FeNiCoCrMo12)Al16 and (FeNiCoCrMo12)Al22, the best composition for the manufacture of the powder was chosen in terms of the parameters of hardness and stability of the structure after annealing. A powder of the composition (FeNiCoCrMo12)Al22 was obtained and investigated by atomizing. The powder has a microhardness of 842 HV and a single-phase BCC structure with a small degree of ordering. However, after heating to 900Â°C, the microstructure acquires phases that were in the cast sample with 22% Al after heat treatment: BCC, B2, Ï¬.
