From: Direct measurement of nanostructural change during in situ deformation of a bulk metallic glass
A schematic overview of the experiment. a Annular dark field (ADF) scans taken before, during, and after in situ deformation of a bulk metallic glass sample. The change in the size and shape of the hole is indicative of plastic deformation. The lack of contrast change across the specimen suggests constant sample thickness. The green dashed box shows where NBED was performed. The scale bar is 150 nm. b Schematic showing the NBED process in the metallic glass. As the beam rasters over the area, a full map consisting of over 33,000 nanobeam electron diffraction patterns is recorded. The three patterns shown are examples containing two-fold (orange), four-fold (blue), and zero (yellow) symmetries, respectively
