Comparison of the Strength of Binary Dislocation Junctions in fcc Crystals

Table 1

List of the dislocation interactions and their corresponding reactions. Here both the Burgers vectors and the slip planes are shown for the interacting dislocations and their products. The first reactant dislocation is longer than the other in all the cases.

Interaction type	Dislocation reaction
Lomer	(1/2)[011](111)+(1/2)[101](111)=(1/2)[110](001)
Collinear	(1/2)[110](111)+(1/2)[110](111)=annihilation
Glissile-a	(1/2)[101](111)+(1/2)[110](111)=(1/2)[011](111)
Glissile-b	(1/2)[110](111)+(1/2)[101](111)=(1/2)[011](111)
Coplanar	(1/2)[011](111)+(1/2)[110](111)=(1/2)[101](111)
