Description: In a heavily deformed metal, the dislocation configurations are not simple and so the boundary structures formed during recovery are correspondingly more complex. The dislocations will arrange themselves into complex networks of different Burgers vectors and different types (i.e. edge, screw or mixed). This interactive animation presents five stages of sub-grain formation and polygonisation.
Keywords: sub-grains • polygonisation • Burgers vectors • deformation • dislocations • grain boundaries
