Abstract

In cold-rolled Pd and Pd-H alloys the presence of hydrogen enhances the multiplication of dislocations and leads to an increase in dislocation density as compared to pure Pd. Subsequent removal of H from Pd-H alloys does not influence the dislocation density. H was identified as a temporary alloying addition (defactant) which increases the dislocation density of cold-deformed Pd.
