A Novel Soft‐Magnetic B2‐Based Multiprincipal‐Element Alloy with a Uniform Distribution of Coherent Body‐Centered‐Cubic Nanoprecipitates

Multiprincipal‐element alloys (MPEAs), including high‐entropy alloys, are a new class of materials whose thermodynamical properties are mainly driven by configuration entropy, rather than enthalpy in the traditional alloys, especially at high temperatures. Herein, the design of a novel soft‐magnetic nonequiatomic, quaternary MPEA is described, via tuning its chemical composition to deliberately manipulate its microstructure, such that it...
