Embrittlement-tolerant alloys for safe hydrogen transmission and storage

钢中的氢脆是安全氢经济的主要障碍。该项目将确定氢如何影响钢的变形行为，提供开发可安全用于未来澳大利亚氢气工业基础设施的合金所需的基本信息。我们将利用新技术，首次确定氢原子在微尺度特征周围的位置，并将其与通过微机械测试确定的局部机械行为进行比较。系统地研究氢对钢中不同微观成分的影响，将有助于制定以组织为导向的合金设计原则。

Hydrogen embrittlement in steels is a major impediment to a safe hydrogen economy. This project will determine how hydrogen affects the deformation behaviour of steel, providing the fundamental information that is required to develop alloys that can be safely used in infrastructure for a future Australian hydrogen industry. We will utilise new technologies that allow us, for the first time, to determine the position of hydrogen atoms around micro-scale features and to compare it to local mechanical behaviour, determined by micro-mechanical tests. The systematic investigation of the effect of hydrogen on different micro-components within steel will allow the development of microstructure-guided alloy design principles.
