Data and code underlying the project: Designing hydrogen-resistant alloys through novel multi-scale modeling and experimentation (De-Hy) WP3

This project aimed at understanding the Hydrogen Embrittlement behaviour of Ferritic High Strength Steels through a combination of mechanical testing, thermal desorption spectroscopy (TDS) and several other characterisation techniques like SEM, TEM, SIMS, EBSD, EDS, OM and Hardness testing. These techniques were used to charge several different High Strength Steels with atomic hydrogen, to visualise the hydrogen in the microstructure either directly or indirectly, and finally to assess the influence of the hydrogen on the mechanical properties of the steels. The data files contain the raw test data of all utilised techniques in their respective data types, as well as Python code to process the data. Furthermore it contains the LaTeX files, Python code and Figures used to create three separate published journal papers and a PhD Thesis. Lastly it contains the data used for an internship and MSc thesis project, both of which were also synthesised into a thesis chapter. Common data types are .xlsx, .csv, .oim, .jpg, .tiff, .png, .ai, .ipynb and .py, as well as some file types used by machine specific software packages (ThermoCalc, EC-Lab and OIM Analysis).

本项目旨在解析铁素体高强度钢的氢脆（Hydrogen Embrittlement）行为，通过结合力学测试、热解吸光谱（Thermal Desorption Spectroscopy, TDS）以及扫描电子显微镜（Scanning Electron Microscope, SEM）、透射电子显微镜（Transmission Electron Microscope, TEM）、二次离子质谱（Secondary Ion Mass Spectrometry, SIMS）、电子背散射衍射（Electron Backscatter Diffraction, EBSD）、能量色散X射线谱（Energy Dispersive Spectroscopy, EDS）、光学显微镜（Optical Microscopy, OM）与硬度测试等多种表征手段开展研究。本研究借助上述技术对多组不同牌号的高强度钢开展原子氢充氢实验，以直接或间接的方式可视化微观组织内的氢元素，最终评估氢对钢材力学性能的影响。本数据集包含所有测试手段的原始测试数据，格式匹配各测试方法对应的专属数据类型，同时附带用于数据处理的Python代码。此外，数据集还包含用于撰写3篇已发表期刊论文与1篇博士学位论文的LaTeX文件、Python代码与配图文件。最后，数据集还涵盖了实习项目与硕士学位论文项目所用的数据，二者均被整合为一篇学位论文章节。数据集常用的数据格式包括.xlsx、.csv、.oim、.jpg、.tiff、.png、.ai、.ipynb与.py，同时包含部分专用软件配套的文件格式（如ThermoCalc、EC-Lab与OIM Analysis）。
