Wootz steel project by electron backscatter diffraction

The data is from an electron backscatter diffraction (EBSD) study of the microstructure of high carbon ‘Wootz’ steel. The objective of the study is to infer an unknown thermomechanical history from observation and analysis of the final microstructure in various ancient artefacts (swords and tools), and then compare the findings with heat treatments of the ancient artefacts and modern attempts at duplication of the structure. Electron backscatter data reveals the orientation relationships between various phases in the material, particularly cementite and ferrite. The dataset is randomly structured and organised. The data is automatically generated by an electron backscattered diffraction system attached to a field emission scanning electron microscope. The dataset uses proprietary software (cannot be copied or distributed without complying with licensing agreements): Oxford HKL Channel 5. As the native formats are binary they cannot be read with standard software.

本数据集源自对高碳‘Wootz’钢微观结构的电子背散射衍射（EBSD）研究。研究旨在通过对各种古代文物（如剑和工具）最终微观结构的观察与分析，推断出未知的 thermomechanical history（热机械历史），并将所得结论与古代文物的热处理方法及现代对结构复制的尝试进行对比。电子背散射数据揭示了材料中不同相之间的取向关系，特别是渗碳体与铁素体的关系。该数据集结构随机，组织有序。数据由附着于场发射扫描电子显微镜的电子背散射衍射系统自动生成。数据集采用专有软件（未经符合许可协议，不得复制或分发）进行处理：牛津HKL Channel 5。由于原始格式为二进制，因此无法使用标准软件进行读取。
