First-principles calculations of transition metal–solute interactions with point defects in tungsten
Xiang-Shan Kong,Xuebang Wu,Yu-Wei You,Changsong Liu,Q.F. Fang,Junling Chen,G.-N. Luo,Zhiguang Wang +7 more
TL;DR: In this paper, a series of first-principles calculations to quantify the intrinsic properties of transition metal (TM) solutes and their interactions with point defects in W, including vacancies and ǫ-crowdions, were performed.
Journal ArticleDOI
First-principles determination of grain boundary strengthening in tungsten: Dependence on grain boundary structure and metallic radius of solute
Xuebang Wu,Yu-Wei You,Xiang-Shan Kong,Junling Chen,G.-N. Luo,Guang-Hong Lu,Changsong Liu,Zhiguang Wang +7 more
TL;DR: In this article, the authors study the effect of transition metals on the grain boundary strengthening of tungsten GBs and uncover its dependence on the GB structures and the radius of the solute itself.
Journal ArticleDOI
First-principles calculations of hydrogen solution and diffusion in tungsten: Temperature and defect-trapping effects
Xiang-Shan Kong,Sheng Wang,Xuebang Wu,Yu-Wei You,Changsong Liu,Q.F. Fang,Junling Chen,G.-N. Luo +7 more
TL;DR: In this article, a series of first-principles calculations were performed to predict the dissolution and diffusion properties of interstitial hydrogen in tungsten and the influence of temperature and the defect-trapping effect.
Journal ArticleDOI
Dissolving, trapping and detrapping mechanisms of hydrogen in bcc and fcc transition metals
Yu-Wei You,Xiang-Shan Kong,Xuebang Wu,Yichun Xu,Q.F. Fang,J. L. Chen,Guang-Nan Luo,Changsong Liu,Bicai Pan,Zhiguang Wang +9 more
TL;DR: In this article, the authors investigated the dissolving, trapping and detrapping of H in six bcc (V, Nb, Ta, Cr, Mo, W) and six fcc (Ni, Pd, Pt, Cu, Ag and Au, Vac-H4 in Cr,Mo, and W, and Vac-6 in V, nb, t, t and Ni.
Journal ArticleDOI
Clustering of H and He, and their effects on vacancy evolution in tungsten in a fusion environment
Yu-Wei You,Dongdong Li,Xiang-Shan Kong,Xuebang Wu,Changsong Liu,Q.F. Fang,Bicai Pan,Junling Chen,G.-N. Luo +8 more
TL;DR: In this paper, the authors carried out density-functional theory calculations to investigate the clustering of hydrogen and helium atoms at interstitial sites, vacancy and small vacancy clusters (Vacm, m = 2, 3), and the influence of the hydrogen atoms on vacancy evolution in tungsten.
