Extended Data Fig. 4 | Serial sections through an APT reconstruction.
a, The (Ni,Fe) 3 Ti precipitates are marked by a 10 at% Ti isocomposition surface
in the APT reconstruction. b, Consecutive slices through the same dataset
from one side of the tip to the other. Each slice is 10 nm thick and all Ti atoms
within this slice are shown. This sequence of images illustrates the complex
shape and morphology and three-dimensional arrangement of the network
of η-phase (Ni,Fe) 3 Ti precipitates created by IHT during the DED process.
c–f, Reconstruction of an APT volume that contains small spherical
precipitates a few nanometres in diameter in addition to the plate-shaped
interconnected network of precipitates. Both precipitate types are η-phase
(Ni,Fe) 3 Ti and are marked by means of 10 at% Ti isocomposition surfaces.
The plate-shaped network is depicted in dark green and the small spherical
precipitates are depicted in light blue. In c, the whole dataset is shown,
and in d–f, only a thin slice of 5 nm thickness is shown. In addition to the
isocomposition surfaces, Ti atoms are shown in d–f. Panels e and f are
enlarged sections of the image shown in c.
