Non-linear jog-dragging effect on the mobility law of edge dislocations in face-centered cubic nickel
Wu-Rong Jian, Yifan Wang, Wei Cai
Dislocation jogs have strong effects on dislocation motion that governs the strain-hardening behavior of crystalline solids, but how to properly account for their effect in mesosca…

Link Statistics of Dislocation Network during Strain Hardening
Sh. Akhondzadeh, Hanfeng Zhai, Wurong Jian +3
Dislocations are line defects in crystals that multiply and self-organize into a complex network during strain hardening. The length of dislocation links, connecting neighboring no…

Room-temperature vacancy emission from the jog on edge dislocation in FCC nickel under glide force
Yifan Wang, Wu-Rong Jian, Wei Cai
Jogs, atomic-scale steps on dislocations, play an important role in crystal plasticity, yet they are often ignored in discrete dislocation dynamics (DDD) simulations due to their s…
