Scanning Electron Microscopy versus Transmission Electron Microscopy for Material Characterization: A Comparative Study on High-Strength Steels

Figure 7

Twinning structures in samples M12 (a, c) and M26 (b, d) imaged with TEM-BF (a, b) and SEM-ECC (c, d). The twin size was between 2 and 10 nm in both TEM-BF and SEM-ECC images, but larger twins were observed by SEM-ECCI. The white arrows point to twinning structures as seen in BF-TEM and ECC images.
