On a mechanism for enhanced hydrogen flux along grain boundaries in metals
Source abstract
Abstract
Abstract Using X-ray diffraction, namely a rocking curve scan, the effect of electrolytic hydrogen charging on the crystal structure in the Fe-36Ni alloy has been studied in comparison with that after gaseous hydrogenation. It is shown that, in contrast to gaseous charging, the electrolytic one induces plastic deformation increasing thereby density of dislocations and causing crystallographic texture. Based on the analysis of available contradictory data on the grain boundary hydrogen diffusion during the measurements of hydrogen permeation and the obtained experimental data, it is proposed that enhanced hydrogen flux along the grain boundaries is due to hydrogen transport by moving dislocations.
