Abstract

Non-destructive, comprehensive dislocations characterization in fine grained Interstitial-Free Steel was realized for the first time by Accurate Electron Channeling Contrast Imaging "A-ECCI" in a Scanning Electron Microscope. Conventional Transmission Electron Microscopy g·b = 0 invisibility criterion and trace analysis were applied to determine Burgers vectors and line directions in this bulk material. This approach relies on the live collection of High Resolution Selected Area Channeling Patterns "HR-SACPs" using an innovative procedure to rock the beam with a remarkable spatial resolution of about 1 μm.
