Hydrogen clustering in bcc metals: atomic origin and strong stress anisotropy
Jie Hou, Xiang-Shan Kong, C. S. Liu +1
Hydrogen (H) induced damage in metals has been a long-standing woe for many industrial applications. One form of such damage is linked to H clustering, for which the atomic origin…
Accurate prediction of nanovoid structures and energetics in bcc metals
Jie Hou, Yu-Wei You, Xiang-Shan Kong +2
Knowledge on structures and energetics of nanovoids is fundamental to understand defect evolution in metals. Yet there remain no reliable methods able to determine essential struct…
Predictive Model of Hydrogen Trapping and Bubbling in Nanovoids in BCC Metals
Jie Hou, Xiang-Shan Kong, Xuebang Wu +2
Interplay between hydrogen and nanovoids, despite long-recognized as a central aspect in hydrogen-induced damages in structural materials, remains poorly understood. Focusing on tu…
Hydrogen bubble nucleation by self-clustering: Density Functional Theory and statistical models studies using tungsten as a model system
Jie Hou, Xiang-Shan Kong, Jingjing Sun +4
Low-energy hydrogen irradiation is known to induce bubble formation in tungsten, while its atomistic mechanisms remain little understood. Using first-principles calculations and st…
Atomistic Mechanism from Vacancy Trapped H/He Atoms to Initiation of Bubble in W under Low Energy Ions Irradiation
Yu-Wei You, Xiang-Shan Kong, Q. F. Fang +5
With the first principles calculations of H and He induced energetics change we demonstrate that in W the accumulation of H (up to 9) and He (up to 4) in a single vacancy (V) surpr…
First principle study of hydrogen behavior in hexagonal tungsten carbide
Xiang-Shan Kong, Yu-Wei You, C. S. Liu +3
Understanding the behavior of hydrogen in hexagonal tungsten carbide (WC) is of particular interest for fusion reactor design due to the presence of WC in the divertor of fusion re…
First principle study of intrinsic defects in hexagonal tungsten carbide
Xiang-Shan Kong, Yu-Wei You, J. H. Xia +4
The characteristics of intrinsic defects are important for the understanding of self-diffusion processes, mechanical strength, brittleness, and plasticity of tungsten carbide, whic…
