Development of multi-scale in situ approaches to understand hydrogen embrittlement of engineering alloys at cryogenic temperatures

氢气是未来净零排放的重要组成部分。低温储罐和分配管被用来在低温下储存和运输/分配液氢，这在航天工业中得到了证明，并将用于未来的氢经济。了解结构合金的氢脆是安全使用氢的关键。该博士项目的目的是通过多尺度的原位力学测试方法，加深对先进材料在低温下的氢脆的了解。拟议的研究包括开发和实施新的原位充氢和机械表征工具和方法。这项工作的成果将对英国经济的绿色增长产生持续的积极影响。

Hydrogen is an essential part of the future of net zero emissions. Cryogenic tanks and distribution pipes are used to store and transport/distribute liquified hydrogen at cryogenic temperatures as demonstrated in space industry and will be used in future hydrogen economy. Understanding hydrogen embrittlement of structural alloys is key for the safe use of hydrogen. The aim of this PhD project is to gain an enhanced understanding of hydrogen embrittlement at cryogenic temperatures of advanced materials via multi-scale in situ mechanical testing methodologies. The proposed research involves the development and implementation of new in situ hydrogen charging and mechanical characterization tools and methods. The results from the work will have continuously positive impact on the green growth of the UK's economy.
