APT. (A) APT images of the CoZrTaB MG with average B-contents of 29.6 at.% (top left) and 27.0 at.% (top right) along the film growth direction. The concentration profiles for Co, Zr, Ta and B are obtained from the APT reconstructions (bottom panels) (Adapted from ref. [136]. Copyright©2016, Elsevier). (B) 3D APT reconstruction (top) and corresponding concentration profiles (bottom) of the ordered Pd_42.5Ni_42.5P₁₅ MG, showing that no phase separation with partitioning of chemical composition after the phase transition (Adapted from ref. [137]. Copyright©2020, Elsevier). (C) 3D APT images of reused ribbons of Fe-based amorphous catalysts (Adapted from ref. [138]. Copyright©2019, Wiley-VCH GmbH). (D) APT volume rendering of Al in a Cu-Zr-Al MG showing the Al precipitation (Adapted from ref. [52]. Copyright©2021, Springer Nature).
