Hydrogen (H), emerging as a sustainable and promising clean energy source, holds
significant potential for transitioning towards a H-based economy, offering a cleaner …

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 …

The influence of grain boundaries (GBs) on hydrogen transportation is a crucial factor in
understanding the mechanisms of hydrogen embrittlement (HE) in polycrystalline alloys …

Hydrogen transport by moving dislocations is one of the key mechanisms for hydrogen
embrittlement, which is considered responsible for local hydrogen accumulation at …

We present a combined phase field and cohesive zone formulation for hydrogen
embrittlement that resolves the polycrystalline microstructure of metals. Unlike previous …

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 …

High-resolution electron backscatter diffraction (HR-EBSD) can provide an estimate of
elastic strains at a microscopic scale. Due to the need for high-quality Kikuchi patterns, HR …

The development of strong textures can affect mechanical anisotropy in the specimens
produced by the laser powder bed fusion (LPBF) additive manufacturing (AM) technique. In …

Hydrogen can strongly embrittle aluminum alloys by accumulating at precipitate interface
and triggering transgranular cracking, due to stress-driven hydrogen diffusion towards crack …

Polycrystalline materials usually exhibit obvious preferred grain orientations (ie,
crystallographic texture) after rolling and heat treatments, leading to a certain crystalline …
