Fig. 2.. Back-scattered electron (BSE) SEM images of as-cast (AlTa_0.76)_xCoCrFeNi_2.1 alloys with x = 0.1 (a), 0.3 (b), 0.5 (c), 0.7 (d), 1.0 (e), and 1.5 (f). Insets of (b), (c) and (d) show secondary-electron (SE) SEM images, and (e) and (f) are BSE SEM images at a higher magnification. The dendrite and interdendrite region are marked in DR and ID, respectively.
