a XRD spectrum illustrating an ordered L12-type crystal structure. b EBSD-IPF map showing the fine grain morphology perpendicular to the building direction (BD), the color representing the crystal orientation. c TEM bright-field image showing the homogenous grain structure, the inset of (c) showing the diffraction pattern of the grain along [001] crystal zone axis, the superlattice diffraction spots highlighted by the yellow circles in the SAED pattern illustrating a highly ordered L12 structure of the grain interior. d 3D-APT results showing the homogeneous elements distribution within the grain interior. e One-dimensional concentration profile showing the element distributions across the 3D-APT tip, the error bar representing the standard deviation of atomic fraction of each element. f Atomic EDS maps taken from the ordered grain interior along the [001] crystal zone axis, showing the spatial occupations of each element.
