In situ phase engineering during additive manufacturing enables high-performance soft-magnetic medium-entropy alloys.

ABSTRACT: Additive manufacturing (AM) shows promise as a method for producing soft-magnetic multicomponent alloys for use in electric motors and sustainable electromobility applications. However, the simultaneous achievement of a high saturation magnetic flux density (B_s) and a low coercivity (H_c) in AM soft-magnetic materials remains challenging. Herein, we present an approach that integrates an elemental powder mixture of Fe₄₅Co₃₀Ni₂₅ with Fe₂O₃ nano-oxides, which is then subjected to laser powder bed fusion (LPBF) followed by high-temperature annealing to achieve an FCC-structured Fe₄₅Co₃₀Ni₂₅ MEA/FeO composite. The FeO nanoparticles, a byproduct of the reaction between Fe powders and Fe<
