Novel Fe2CoNi(AlSi)x high-entropy alloys with attractive soft magnetic and mechanical properties

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 σ0.2 (887.6 MPa), fracture...
