High-entropy alloys have attracted increasing attentions because of their unique compositions, microstructures, and adjustable mechanical and functional properties. In this work, mechanical and magnetic properties of the FeSiBAlNiMo high-entropy alloy were studied in heat-treated conditions. Influence of temperature and time of sintering was investigated. The lowest coercivity H_c=370 A/m was reached at sintering temperature 580°C, during 20 min in Ar/10H₂ atmosphere. Resistivity decreases from R=0.006 Ωcm at 580°C of sintering temperature to R=0.0004 Ωcm at temperature 1100°C. Transverse rupture strength TRS = 340 MPa as well as the Young modulus E=87 GPa were much higher in the case of sintering at 1100°C in comparison to TRS = 5 MPa and E=7.5 GPa at sintering temperature 580°C. Low temperature consolidation made possible to structure recovery and stress relief of amorphous-nanocrystalline structure. Higher temperature above 1100°C induced sintering processes and formation of complex borides.
