Figure 8. TEM characterization of a typical corrosion micropore on the surface of Cr1 HEA. (A) Bright-field TEM image; (B-D) are the high-resolution TEM image obtained from the interface region and the corresponding FFT patterns, respectively; and (E-E7) HAADF-STEM image with the corresponding EDS elemental maps. TEM: Transmission electron microscopy; HEA: high-entropy alloy; FFT: fast fourier transform; HAADF-STEM: high-angle annular dark-field scanning TEM; EDS: energy-dispersive X-ray spectroscopy.
