Electron backscatter diffraction (EBSD) is a scanning electron microscopy (SEM) technique used to study the crystallographic structure of materials. EBSD is carried out in a scanning electron microscope equipped with an EBSD detector comprising at least a phosphorescent screen, a compact lens and a low-light camera.

在EBSD数据分析中，GOS (grain orientation spread) map常被用来表征金属材料组织的局部应变，利用这种局部应变我们不仅可以区分晶粒内应变的大小，还能用于区分部分再结晶组织中的各晶粒是否为再结晶长大的晶粒，从而表征部分再结晶组织。 这个教程给大家讲解下在OIM analysis中如何生成GOS map来表征和统计部分再结晶组织中的再结晶、回复和变形区域。 01 选中数据，生成GOS map. 02 点击edit按钮，将弹出对话框中的颜色范围数n设置为3，然后点击add n solid …

EBSD在数据处理时，可得到各个滑移系的Schmid Factor图，还能够对施密特因子值进行统计，从而可以判断该合金变形启动那些滑移系。 这对于做模拟计算的科研friends们大有好处。

2024年5月28日 · 电子背散射衍射（Electron Back Scatter Diffraction, EBSD）是一项在扫描电镜中获得样品晶体学信息的技术。 EBSD利用背散射电子衍射，获取晶体取向（crystal orientation）、晶界取向差（grain boundary misorientations），物相等晶体学信息。 EBSD保留了扫描电子显微镜的特点，与金相、XRD、SEM等表征手段相比，其可获取更为丰富、精度更高的晶体学信息，从而可对样品表面的特征进一步分析。 图1. 02电子背散射衍射（EBSD）基本原 …

Maps are the most common way to represent EBSD data. The technique, with the rapid automated collection of orientation and phase data from a grid of points on the surface of a sample, lends itself to the display of data in map form.

2016年7月1日 · EBSD is a commonly used technique that fundamentally interprets a diffraction pattern to understand the unit cell many times to generate rich microstructure maps. In light of increasing access to data, as well as new and exciting data analysis strategies, it is important that both users and manufacturers offer suitable descriptors of their data.

Electron backscatter diffraction (EBSD) maps recorded in various weld regions of friction-stir-welded AA2024 alloy: (a) the parent alloy; (b) the HAZ; (c) the TMAZ; and (d) the nugget region 3

EBSD data processing enhances EBSD analysis with noise reduction and pattern indexing, generating EBSD maps such as EBSD orientation maps and EBSD IPF maps.

2022年2月9日 · Another very useful map that is almost always generated using EBSD analysis tools is called band contrast map or pattern quality map, depending upon the manufacturer of the instrument. The primary information displayed in these maps is the contrast or average intensity of the Kikuchi bands for each and every point.

A quick guide on how to import and make basic plots with EBSD data in MTEX. Data import. MTEX allows you to import EBSD from all big vendors of EBSD systems. Prefered data formats are text based data files like .ang, .ctf or open binary formats like .osc or .h5. Most conveniently, EBSD data may be imported using the import wizard, by typing ...
