Abstract
A new method of hydrogenation and quenching of metals in liquid hydrogen, i.e. the hydrogen quenching method, is developed and applied to investigate the recovery of pure iron after the hydrogenation and quenching by measuring the electrical resistivity change during annealing at higher temperatures. A new stage corresponding to the migration and disappearance of solute hydrogen atoms in pure iron appears in the resistivity decay curve, and by an approximate analysis based upon the rate process calculation the migration energy of single interstitial hydrogen atoms is determined to be 2.2±0.2 kcal/mol. In the diffusion process, most of the solute hydrogen atoms are discharged at the free surface of the specimen, but, in order to fully explain the resistivity decay curves, the influence of trapping sites or sinks for hydrogen in the interior must be also considered.
