Fig.3 Bright-field TEM images and corresponding SAED patterns and grain size distributions with normal fitting (insets) (a, c, e) and HRTEM images (b, d, f) of melt-spun Fe_{98.5 -}_x B _x Cu_1.5 alloys with x = 12 (a, b), x = 15 (c, d), and x = 18 (e, f) ( $d_{{(100)}_{α ‐ F e}}$ —grain size of α-Fe grains for the melt-spun alloys, N—normal distribution; dashed areas show the pre-existing α-Fe nanograins)
