Abstract

Pattern matching approaches to electron backscatter diffraction (EBSD) in the scanning elec-tron microscope (SEM) provide qualitatively new possibilities for the microstructural analysis of chiral non-centrosymmetric phases due to the influence of dynamical electron diffraction effects on the formation of EBSD Kikuchi patterns. In the present study, we analyze the mi-crostructure of polycrystalline α-quartz in an agate mineral sample. We identify characteristic intra-grain inversion domains of different handedness which are well-known from classical po-larized light microscopy. As a result, the handedness-resolved microstructure of quartz can be imaged with the spatial and orientation resolution provided by EBSD in the SEM.

EBSD数据分析的模式匹配工作流：石英手性映射

扫描电子显微镜（SEM）电子背散射衍射（EBSD）的模式匹配方法为手性非中心对称相的微观结构分析提供了定性的新可能性，因为动态电子衍射效应影响了EBSD菊池图案的形成。本文研究了玛瑙矿物样品中多晶α-石英的微观结构。我们确定了典型的不同手性的颗粒内反转域，这是众所周知的经典偏光显微镜。结果表明，利用EBSD提供的空间和取向分辨率，可以对石英的手性分辨微观结构进行成像。

期刊介绍： Materials Characterization features original articles and state-of-the-art reviews on theoretical and practical aspects of the structure and behaviour of materials. The Journal focuses on all characterization techniques, including all forms of microscopy (light, electron, acoustic, etc.,) and analysis (especially microanalysis and surface analytical techniques). Developments in both this wide range of techniques and their application to the quantification of the microstructure of materials are essential facets of the Journal. The Journal provides the Materials Scientist/Engineer with up-to-date information on many types of materials with an underlying theme of explaining the behavior of materials using novel approaches. Materials covered by the journal include: Metals & Alloys Ceramics Nanomaterials Biomedical materials Optical materials Composites Natural Materials.
