Fig.7 Solid-liquid interfacial morphologies of Fe7(CoNiMn)80B13 eutectic high-entropy alloys under ΔT = 23 K (a), ΔT = 111 K (b), and ΔT = 154 K (c) (Red dashed lines and red arrow in Fig.7a show the solid-liquid interface and the growing direction of the solid phase, respectively. Circles with yellow, blue, and green colors in Fig.7b represent three nucleation points in the melt)
