The microstructures of FeCoNiCrCu high entropy alloy were investigated under directional solidification. The results showed that only diffraction peak corresponding to a FCC crystal structure was observed in the directionally solidified FeCoNiCrCu alloy. With increasing solidification rate, the interface morphology would grows in planar, cellular and dendrite. Comparing the potentiodynamic polarization of as-cast and directionally solidified FeCoNiCrCu high entropy alloy in a 3.5%NaCl solution, it is clearly reveals that the corrosion resistance of directionally solidified FeCoNiCrCu alloy is superior to that of the as-cast FeCoNiCrCu alloy.
