Abstract:By analyzing the experimental data on the influence of gaseous hydrogen on physicomechanical properties of steels, we consider the mechanism of reversible hydrogen embrittlement, focus our attention on the processes of surface interaction, and explain the surface-active properties of hydrogen. The low solubility, high mobility, and affinity to metals characterize hydrogen as the most efficient surface-active element with respect to metals. We propose to consider the ability of hydrogen to concentrate in certai… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
