We present a series of tools working together that facilitate the determination of dislocation Burgers vectors and slip planes, interface plane normals, and misorientation between two crystals from a series of TEM micrographs and diffraction patterns. To that purpose, we developed graphical user interface programs that allow crystal orientation determination from spot diffraction patterns taken at various tilt angles or from Kikuchi patterns, crystal representation from stereographic projection plots, and determination of geometrical features from series of conventional images taken at different tilt angles. We present working examples that allow a faster and easier way to analyze data that can especially be retrieved during in-situ straining experiments where dislocations and grain boundaries need to be characterized. More generally, these tools target material scientists interested in daily microstructural characterization in TEM. This article is protected by copyright. All rights reserved.

pycotem：一个开源工具箱，用于通过 TEM 成像和衍射进行在线晶体缺陷表征

我们展示了一系列协同工作的工具，这些工具有助于从一系列 TEM 显微照片和衍射图案中确定位错伯格矢量和滑移平面、界面平面法线以及两个晶体之间的错误取向。为此，我们开发了图形用户界面程序，允许从以不同倾斜角度拍摄的点衍射图案或菊池图案确定晶体取向、立体投影图的晶体表示，以及从以不同倾斜角度拍摄的一系列常规图像确定几何特征角度。我们提供了一些工作示例，这些示例可以更快、更轻松地分析数据，尤其是在需要表征位错和晶界的原位应变实验中检索到的数据。更普遍，这些工具针对对 TEM 中的日常微观结构表征感兴趣的材料科学家。本文受版权保护。版权所有。
