AbstractAlCoCrFeNi2.1 eutectic high entropy alloy (EHEA) has attracted significant interest among researchers due to unprecedented mechanical properties compared with single-phase solid solution high entropy alloys; however, the high content of cobalt element limits its engineering applications. In this paper, the mechanical and corrosion behaviors of cost-effective AlCrFeNi3.1 and AlCrFe2Ni2.1 HEAs were systematically studied by tensile tests and electrochemical methods; meanwhile, the results were compared with AlCoCrFeNi2.1 EHEA. The results indicated that all the studied HEAs showed dual phase microstructure composed of FCC and BCC/B2 phases. Due to the hetero-deformation induced strengthening, all the studied HEAs showed an excellent combination of strength and ductility with fracture strength over 1 GPa and fracture strain exceeding 17%, indicating that substituting the cobalt element of AlCoCrFeNi2.1 EHEA by nickel or iron element is feasible from the perspective of mechanical properties. As for the corrosion behaviors in 3.5 wt.% NaCl solution, AlCrFeNi3.1 HEA exhibited the best corrosion resistance due to the high volume fraction of the corrosion resistant FCC phases and low Al/Cr ratio of BCC/B2 phases, while AlCrFe2Ni2.1 HEA showed the worst corrosion resistance owing to the high Al/Cr ratio of BCC/B2 phases.
