Fig. 3: Chemical and atomic structures of the DINL and ordered grain interior.
From: Highly printable, strong, and ductile ordered intermetallic alloy
a 3D-APT maps showing the distribution of each element near the grain boundary. Elements Co and B co-segregated to the DINL, while Ni, Si, Ti, and Al depleted accordingly. b One-dimensional compositional profile revealing the elemental distributions across the grain interior and DINL, the error bar representing the standard deviation of atomic fraction of each element. c Atomic-resolution STEM-HAADF image illustrating the atomic structures of the DINL and grain interior, the corresponding FFT images (insets in c) showing the disordered structure of the DINL and ordered structure of grain interior.
