Abstract Orientation determination does not necessarily require complete knowledge of the local atomic arrangement in a crystalline phase. We present a method for microstructural phase discrimination and orientation analysis of phases for which there is only limited crystallographic information available. In this method, experimental Kikuchi diffraction patterns are utilized to generate a self-consistent master reference for use in the technique of Electron Backscatter Diffraction (EBSD). The experimentally derived master data serves as an application-specific reference in EBSD pattern matching approaches. As application examples, we map the locally varying orientations in samples of icosahedral quasicrystals observed in a Ti40Zr40Ni20 alloy, and we analyse AlNiCo decagonal quasicrystals.

基于实验菊池参考图案的 EBSD 取向分析

摘要 方向确定不一定需要完全了解晶相中的局部原子排列。我们提出了一种用于相的微观结构相鉴别和取向分析的方法，其中只有有限的晶体学信息可用。在这种方法中，实验性的菊池衍射图案被用来生成一个自洽的主参考，用于电子背散射衍射 (EBSD) 技术。实验得出的主数据用作 EBSD 模式匹配方法中特定于应用程序的参考。作为应用示例，我们绘制了在 Ti40Zr40Ni20 合金中观察到的二十面体准晶样品中局部变化的取向，并分析了 AlNiCo 十边形准晶。
