The successful realization of a hydrogen economy is crucially dependent on a
comprehensive understanding of the effects of hydrogen on the hydrogen infrastructure …

Hydrogen is considered a clean and efficient energy carrier crucial for shaping the net-zero
future. Large-scale production, transportation, storage, and use of green hydrogen are …

Premature failure due to hydrogen has been widely observed in different metallic materials.
How does hydrogen affect the competition between brittle cleavage and ductile fracture is an …

The presence of hydrogen atoms in the lattice of polycrystalline metals can lead to hydrogen
embrittlement. The diffusion of hydrogen atoms and formation of hydrides depend on several …

In an attempt to bridge the gap between atomistic and continuum plasticity simulations of
hydrogen in iron, we present three dimensional discrete dislocation plasticity simulations …

The exceptional combination of strength and ductility in multi-component alloys is often
attributed to the interaction of dislocations with the various solute atoms in the alloy. To study …

A new computational methodology for 3-dimensional (3D) Discrete Dislocation Dynamics
(DDD) in barrier-strengthened materials is developed. We couple the discrete 3D DDD …

Understanding of years-old multifaceted hydrogen-assisted damage evolution necessitates
efforts to model the coupled diffusion-mechanics response in metallic materials. Informed by …

In this study, the deformation microstructure of hydrogen-charged ferritic-pearlitic 2Mn-0.1 C
steel was characterized using SEM-BSE, SEM-EBSD, TEM, and neutron diffraction. The …

Multiscale impact of dislocation patterns on hydrogen diffusion and trapping mechanisms
has been investigated in multi-slip tensile strengthening nickel single crystal. A thorough …
