Figure 1. (A) Schematic diagram of B₂O₃ fluxing experiment setup (left). Photograph of alloy ingot showing the morphology of the specimen after fluxing (units: cm) (right). (B) Solidification process of molten alloy droplet, showing the recalescence phenomenon. (C) Cooling curve of [(FeNiCo)_0.85Cr_0.15]₈₃B₁₇ N-HEA melt. The red arrow indicates the occurrence of recalescence. (D) DSC curves of [(FeNiCo)_0.85Cr_0.15]_100-xB_x (x = 12, 15, 17) N-HEAs during cooling process. The black arrow indicates the liquidus temperature of [(FeNiCo)_0.85Cr_0.15]₈₃B₁₇ N-HEA.
