Hydrogen embrittlement of metallic components
One of the key directions of our research focuses on hydrogen embrittlement (HE), a critical phenomenon threatening the integrity of metallic components in hydrogen storage and transport infrastructure. As hydrogen emerges as a clean energy carrier, the degradation of metallic components caused by HE threatens the integrity and safety of hydrogen transport and storage infrastructure. HE occurs when hydrogen atoms diffuse into metals, reducing their ductility, strength, and fracture toughness, ultimately leading to premature failure.

Addressing HE is pivotal for advancing green energy solutions. Metallic pipelines, storage tanks, and pressure vessels are essential for hydrogen infrastructure but remain vulnerable to hydrogen-induced damage. Developing a fundamental understanding of HE mechanisms is crucial to designing materials that can resist such degradation.

Our research seeks to elucidate the mechanistic basis of hydrogen embrittlement by studying hydrogen diffusion, trapping, and their interaction with microstructural features like dislocations, grain boundaries, and voids. To model hydrogen-assisted cracking interfaces, we utilise phase field theory, a powerful mathematical framework that regularises evolving crack interfaces and provides deep insights into crack initiation and propagation in the presence of hydrogen.

A key focus is the investigation of hydrogen embrittlement in pipeline infrastructure to ensure the safe transport and storage of hydrogen. By examining the interplay between material properties, operating conditions, and environmental factors, we aim to develop predictive models and innovative solutions for HE mitigation.

Our work combines cutting-edge computational methods, such as phase field theory, with experimental insights to bridge the gap between fundamental research and practical applications. We aim to inspire young researchers to contribute to this exciting field at the intersection of materials science, mechanics, and green energy technologies, ultimately supporting the global transition to a sustainable future.
