Abstract
Absorption of edge dislocations in tilt grain boundaries (GBs) was studied by atomistic simulations in Al. The process of accommodation of dislocations in GBs and their evolution were analyzed based on atom rearrangement in GBs. It shows that the absorption is realized through both atom motion along the GB which is in perpendicular to the slip plane and structural neutralization of the dislocation core with the local GB core.
