Summary:Заглавие с экрана
The results of first-principle calculations of diffusion barriers for hydrogen atoms in the alpha-phase of zirconium have been presented. It has been obtained that the transition "tetrahedral -octahedral -tetrahedral interstitial sites" can be considered as main in the mechanism of hydrogen diffusion. It has been shown that lattice relaxation induced by hydrogen saturation influences weakly on the form and height of diffusion barriers.
