Hydrogen-induced lattice cohesion weakening favors atomic displacement
Liang Gao, Yiran Mao, Markus Wilde +9
Atomic displacement -- the fundamental process underlying diverse deformation and damage phenomena in metals, from irradiation defect production to stress-driven dislocation motion…

Stress-triggered atomic explosion of trapped hydrogen initiates crack nucleation
Liang Gao, Thomas Schwarz-Selinger, Martin Balden +6
Hydrogen embrittlement (HE) has persisted for more than a century as one of the most intractable problems in materials science. The prevailing view1 that diffusive H governs embrit…

Damage dose dependence of deuterium retention in high-temperature self-ion irradiated tungsten
Mikhail Zibrov, Thomas Schwarz-Selinger, Michael Klimenkov +1
Recrystallized tungsten (W) samples were irradiated by 20 MeV self-ions at 1350 K to peak damage doses in the range of 0.001-2.3 dpa. The irradiation-induced defects were then deco…
