摘要: 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” a Scanning Microscope. Conventional Transmission Microscopy g·b = 0 invisibility criterion and trace analysis were applied to determine Burgers vectors line directions this bulk material. This approach relies on live collection of High Resolution Selected Area Patterns “HR-SACPs” using an innovative procedure rock beam with remarkable spatial resolution about 1 μm.
