# Standard-Based EBSD: Fingerprinting of Order and Orientation in Materials

## TL;DR

This paper introduces a new EBSD-based method that uses experimental Kikuchi patterns to generate standards for phase discrimination and orientation analysis in materials with limited atomic information, demonstrated on quasicrystals.

## Contribution

It presents a novel approach for microstructural analysis that does not require complete atomic arrangement knowledge, enhancing EBSD applicability.

## Key findings

- Successfully mapped orientations in quasicrystals.
- Demonstrated phase discrimination with limited atomic info.
- Validated method on Ti40Zr40Ni20 alloy samples.

## Abstract

Orientation determination does not necessarily require complete knowledge of the local atomic arrangement in a material. We present a method for microstructural phase discrimination and orientation analysis of phases for which there is only limited information available. In this method, experimental Kikuchi diffraction patterns are utilized to generate self-consistent standards for use in the technique of Electron Backscatter Diffraction (EBSD). As an application example, we map the locally varying orientations in samples of icosahedral quasicrystals observed in a Ti40Zr40Ni20 alloy.
