This study investigates the interfacial reaction between an as-cast multicomponent FeCrNiCoMnAl high-entropy alloy (HEA) and an Al melt at 700°C. The microstructure, phase identification, and chemical composition were analyzed by using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), transmission electron microscopy (TEM) and electron back scattering diffraction (EBSD). The results showed that the contact between the solid substrate and the Al melt resulted in the formation of a region with complicated microstructure at the interface. The dissolution of the substrate alloying elements into the Al melt also caused chemical composition and phase changes in the solidified Al crust.
