Figure 11. Phase images of the oxygen-doped TiZrNb medium-entropy alloy viewed along the [110] zone axis[94]. (A) The phase image reconstructed via the APP algorithm, the inset shows the corresponding diffractogram, indicating an information limit of 0.5 Å; (B) Comparison between the reconstructed phase images and the structure models with interstitials, indicating that oxygen interstitials mainly occupy the tetrahedral sites.
