a An IPF-Z map of the microstructure of the Ti0.24CoFeNi0.78 alloy. b A BSE micrograph showing the fine-scale L12 precipitates. c A dark-field TEM micrograph showing the L12 precipitates. d SAEDPs recorded along the <011> BCC zone axis, showing additional {001} and {011} reflections from the ordered L12 precipitates. A 10-nm-thick slice of the 3D reconstructed APT analysis volume displaying e Ti atom map (top), and the Fe and Co atom maps superimposed with 15 at.% Ti iso-concentration surface (bottom) clearly confirms the presence of nano-scale Ti-rich L12 precipitates, and f the corresponding chemical concentration profiles for all the constituent elements present in the alloy across the FCC/L12 interfaces.
