This is illustrated for an edge dislocation. · The atomic structure is only adjusted in the region of the dislocation line during this motion. From: Hull, "Introduction to Dislocations," Pergamon ...

The diagram shows the effect of 'sliding' an Edge (a), Screw (b), or Mixed (c) dislocation completely across a slip plane in the crystal. Each dislocation has the same effect as it moves completely ...

Recent research has focused on understanding the role of dislocations—defects in the crystal structure of solid helium ... cores of hexagonal close-packed (hcp) ^4He. This study utilized ...
