Abstract
The hydrogen effect on the mechanical properties of aluminum was studied using an in situ electrochemical nanoindentation setup. The adsorption of hydrogen ions at the open circuit potential in a solution at pH 6 (less than the isoelectric point = 9.5) resulted in a change of pop-in load. Similar behavior was observed in a solution at pH 9 under cathodic polarization. The change in pop-in load is attributed to the hydrogen-induced reduction of cohesive energy and hydrogen segregation on dislocations.
