A step where a dislocation jumps planes

In the theory of dislocations, a jog is a short step in a dislocation line that carries the line from one glide plane to an adjacent one, as distinct from a kink, which is a step lying within the glide plane. Hirth and Lothe's Theory of dislocations and Hull and Bacon's Introduction to dislocations set out how jogs form when dislocations intersect and how a moving jog drags behind it a trail of vacancies or interstitials, impeding glide. The referent is a localized out-of-plane step on a dislocation, counted per unit length and described by its height, and it anchors how work hardening and point-defect generation are explained in deforming crystals.[1][2]

Unit
The density and height of out-of-plane steps along a dislocation line
Recovery means
Not applicable
Measured by
Observed by transmission electron microscopy and inferred from hardening and point-defect production during deformation
