A ductile high entropy alloy with attractive magnetic properties

FeCoNiMn0.25Al0.25 high entropy alloy was investigated thoroughly in this paper from crystal structure to magnetic and mechanical properties. We found that this alloy formed simple face centered cubic structure which was very stable to deformation and heat treatment. Moreover, this alloy showed high saturated magnetization, low coercivity, high Curie temperature as well as good tensile ductility. This high entropy alloy shows soft magnetic properties much better than most high entropy alloys reported previously. This study suggests that the FeCoNiMn0.25Al0.25 high entropy alloy has the potential for use as soft magnets in the future.
