Fig. 3: In situ TEM observation of coupled glide: experimental observation of dislocation glide at different time steps.

From: Repulsion leads to coupled dislocation motion and extended work hardening in bcc metals

Fig. 3

Reference points are indicated by ʻx, y, z’. a Dislocation Ia approaches the still dislocation II. b–d Dislocation Ia pushes dislocation II: their point of closest distance moves along the direction ʻnode path’ until it emerges at the bottom surface in (e). f, g Another dislocation Ib pushes dislocation II. h Difference-image showing the motion between (b) (black dislocations) and (d) (bright dislocations). i Scheme corresponding to (h).
