Abstract

The effect of Al and Si on microstructure evolution, mechanical, magnetic properties, and electrical resistivity of non-equimolar Fe₂CoNi(AlSi)_x (x = 0–0.4) high-entropy alloys (HEAs) was studied. This series of Fe₂CoNi(AlSi)_x HEAs has a dual-phase structure and shows an excellent combination of mechanical and soft magnetic properties. In particular, the Fe₂CoNi(AlSi)_0.4 HEA exhibits high compressive yield strength σ_0.2 (887.6 MPa), fracture strain (39%), electrical resistivity ρ (84.8 μΩ cm), M_s (155.2 emu/g), and H_c (1.7 Oe). This work may provide a promising method of developing HEAs with an optimal balance of mechanical and soft magnetic properties under the addition of Al and Si suitable for wide-range industrial applications.
