The diagram shows the location of atoms close to an edge dislocation line that runs back into the screen. The green circle outlines a group of atoms close to the dislocation line that have larger ...

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 ...

Where a screw dislocation terminates in a crystal face, an exposed edge is formed which, while growing, will persist and develop as a ‘growth spiral’ centred on the dislocation. This theory ...
