Grain-boundary activated pyramidal dislocations in nano-textured Mg by molecular dynamics simulation

► First- and second-order pyramidal 〈 c + a〉 slip occurs in Mg. ► The first-order edge dislocation can take place with a long stacking fault (SF). ► The first-order edge dislocation has two phases at high stress. ► The second-order 〈 c + a〉 edge dislocation core with edge type is sessile. ► The seco...
