The microstructure and tensile deformation behavior of a Fe2.5Ni2.5CrAl multi-principal element alloy (MPEA) were investigated. The combined effect of the soft FCC phase and the hard BCC + B2 microconstituent resulted in a best-in-class strength-ductility combination. The stress–strain relationship...
