- Lomer-Cottrell_junction abstract "In materials science, a Lomer-Cottrell junction is a particular configuration of dislocations.When two perfect dislocations encounter along a slip plane, each perfect dislocation can split into two Shockley partial dislocations: a leading dislocation and a trailing dislocation. When the two leading Shockley partials combine, they form a separate dislocation with a burgers vector that is not in the slip plane. This is the Lomer-Cottrell dislocation. It is sessile and immobile in the slip plane, acting as a barrier against other dislocations in the plane. The trailing dislocations pile up behind the Lomer-Cottrell dislocation, and an ever greater force is required to push additional dislocations into the pile-up.ex. FCC lattice along {111} slip planes |leading| |trailing|Combination of leading dislocations:The resulting dislocation is along the crystal face, which is not a slip plane in FCC at room temperature.Lomer-Cottrell dislocation".
