· Dislocation motion in crystals can occur when a shear stress act across the slip plane. This is illustrated for an edge dislocation. · The atomic structure is only adjusted in the region of the ...

Climb is the motion of an edge dislocation normal to its slip plane. The process requires the addition or removal of atoms from the extra half plane of the dislocation by diffusion processes. Climb is ...

For decades researchers have studied materials from structures to see why and how they fail. Before catastrophic failure, there are individual cracks or dislocations that form, which are signals that ...
