Fig. 3

a Virtual annular dark-field image acquired directly from the EMPAD’s software showing the field-of-view of a single Han precipitate. Note that this precipitate is the same one at the center of Fig. 1a. b, d The NBED + PCA and NBED + NMF clustering results, respectively, and c, e the corresponding cluster-averaged NBED patterns. Scale bars are 10 nm−1.
