Non-equiatomic FeMnCrNiAl high-entropy alloys with heterogeneous structures for strength and ductility combination

The development of sound cost-effective alloys is always the pursuit of engineering application materials. A non-equiatomic FeMnCrNiAl high-entropy alloy (HEA) has been processed by cold rolling and annealing to prepare samples with a fully-recrystallized structure, and composite structures of recovered and recrystallized structures. The composite structure with a dual heterogeneous structure of both the matrix and precipitates can be designed...
