Effects of the Be 22 W phase formation on hydrogen retention

发布时间：2021-03-28 16:10

　　We have performed first-principles density functional theory calculations to investigate the retention and migration of hydrogen in Be₂₂ W, a stable low-W intermetallic compound. The solution energy of interstitial H in Be₂₂ W is found to be 0.49 eV lower, while the diffusion barrier, on the other hand, is higher by 0.13 eV compared to those in pure hcp-Be. The higher solubility and lower diffusivity for H atoms make Be₂₂ W a potential beneficial secondary phase ...
