H induced decohesion of an Al grain boundary investigated with first principles: Proposed general conditions for instant breakage and delayed fracture
Flemming J. H. Ehlers, Mahamadou Seydou, David Tingaud +3
The uniaxial tensile test response of a H decorated 5 [100] twist grain boundary (GB) in face-centered-cubic Al has been examined with first principles. The impurity shows a st…
