The interplay between thermomigration and stress-driven hydrogen transport in metals
Daniel J. Long, Edmund Tarleton, Alan C. F. Cocks +1
Thermomigration is the driving force for hydrogen transport due to a temperature gradient. It can compete with hydrogen transport induced by stress gradients. While stress-driven h…
Direct Imaging of Hydrogen-Driven Dislocation and Strain Field Evolution in a Stainless Steel Grain
David Yang, Mujan Seif, Guanze He +9
Hydrogen embrittlement (HE) poses a significant challenge to the durability of materials used in hydrogen production and utilization. Disentangling the competing nanoscale mechanis…
A Thermodynamic Model for Thermomigration in Metals
Daniel J. Long, Edmund Tarleton, Alan C. F. Cocks +1
We investigate the mechanisms involved in the thermomigration of interstitial hydrogen in metals. Using irreversible thermodynamics, we develop a comprehensive mechanistic model to…
The link between Microstructural Heterogeneity, Diffusivity, and Hydrogen Embrittlement
Daniel J Long, Edmund Tarleton, Alan CF Cocks +1
Green hydrogen is likely to play a major role in decarbonising the aviation industry. It is crucial to understand the effects of microstructure on hydrogen redistribution, which ma…
