Energetics of hydrogen impurities in aluminum and their effect on mechanical properties

, 2001
The effects of hydrogen impurities in the bulk and on the surface of aluminum are theoretically investigated. Within the framework of density functional theory, we have obtained the dependence on H concentration of the stacking fault energy, the cleavage
