Ultrastrong and ductile bulk high-entropy Fe-Co-Ni-Al-Ta alloy with excellent soft magnetic properties were obtained by introducing a high volume fraction of coherent and ordered nanoprecipitates into the alloy matrix. The high coherency between the homogeneously dispersed nanoprecipitates and the alloy matrix contributed significantly to increase the mechanical properties without affecting the magnetic domain wall motion, preserving soft magnetic behavior. This work was led by the colleagues at Max-Planck Institute for Iron Research (MPIE – Düsseldorf).
