Abstract Based on fundamental difference in diffusion mechanisms of substitutional and interstitial atoms and using molecular dynamics simulation of hydrogen migration, it is shown that accelerated hydrogen flux in the polycrystalline iron, as observed in the course of cathodic charging, cannot originate from the enhanced hydrogen grain boundary diffusion. A possible role of grain boundary cracking is supposed.
