Figure 3. SEM images showing morphology of bulk [(FeNiCo)0.85Cr0.15]100-xBx (x = 12, 15, 17) N-HEAs prepared by suction casting after arc melting for x = 17 (A), and by the fluxing method for x = 12 (B), x = 15 (C), and x = 17 (D). The phase fractions obtained by SEM image processing are superimposed in the figures for direct comparison.
