From: Effects of precipitates and dislocation loops on the yield stress of irradiated iron
Close-up look at the 3D structure of a dislocation system with strong precipitates at a strain of ε = 0.63%. Dislocations (green lines) evolve into a complex network where they pin to each other forming junctions. Dislocations that have bypassed precipitates (red spheres) have left Orowan loops around some of the obstacles. In the inset there is an example of a twisted noose where the edge arms of the loops are on different glide planes and thus cannot annihilate each other.
