Designing High-Strength Steels Resistant to Hydrogen Embrittlement. In the emerging hydrogen economy, addressing hydrogen embrittlement (HE), which causes unpredictable fractures in metallic materials

Description

Designing High-Strength Steels Resistant to Hydrogen Embrittlement. In the emerging hydrogen economy, addressing hydrogen embrittlement (HE), which causes unpredictable fractures in metallic materials, has become a critical priority for safe hydrogen storage, transport, and applications. This project aims to advance the fundamental understanding of the HE mechanism and resolve conflicts in existing theories based on recent breakthrough. Cutting-edge microscopy methodologies will be developed to achieve multi-scale characterisation of the materials, focusing on crack initiation and propagation, and lattice defect-hydrogen interactions. This project aims to design novel HE-resistant, high-strength martensitic steels using a mechanism-based, simulation-guided alloy design approach.. Scheme: Linkage Projects.
