Positron is an excellent probe of lattice defects in solids. A thermallized positron delocalized
in lattice can be trapped at open volume defects, eg vacancies, dislocations, grain …

Tungsten (W) is considered to be one of the most promising plasma-facing materials (PFMs)
for next-step fusion energy systems. However, as a PFM, W will be subjected to extremely …

This study investigated the hydrogen embrittlement of a high strength Zr or Cr-added
aluminum alloy specimens containing coherent Al 3 Zr or incoherent Al 18 Mg 2 Cr 3 …

The pursuit of strong and ductile Al alloys with superior resistance to hydrogen embrittlement
(HE) is practically significant across the aerospace and transportation industries among …

Cyclic oxidation of β-NiAl alloys doped with different reactive elements (REs) each of which
had an optimized concentration was investigated. All of REs effectively suppressed growth …

The interplay between hydrogen and nanovoids, despite long being recognized as a central
factor in hydrogen-induced damage in structural materials, remains poorly understood …

The nature of hydrogen traps and hydrogen embrittlement (HE) behavior of a 7xxx series
aluminum alloy with different microstructural characteristics were investigated. Hydrogen …

We investigate the physical origin of H–He interaction in W in terms of optimal charge
density by calculating the energetics and diffusion properties using a first-principles method …

Hydrogen solubility and interaction with vacancies and divacancies are investigated in 12
fcc metals by density functional theory. We show that in all studied fcc metals, vacancies trap …

Understanding the hydrogen solution and diffusion behaviors are crucial to design the
hydrogen embrittlement resistant structural materials in industry applications. Whether there …
