Polygonization

polygonization

[pə‚lig·ə·nə′zā·shən]
(solid-state physics)
A phenomenon observed during the annealing of plastically bent crystals in which the edge dislocations created by cold working organize themselves vertically above each other so that polygonal domains are formed.

Polygonization

 

the second stage in the return of metals. Upon heating after large deformations, polygonization is, as a rule, an initial stage in recrystallization of metals.

Polygonization (Sub-grain formation and Sub-grain growth).
This procedure or phenomenon is termed polygonization, as a smoothly curved lattice vector in the crystal turns into fraction of a polygon.
You have to understand polygonization procedure in conditions of the dislocation distribution.
Afterward stages of polygonization happen by progressive merging of pairs of nearby boundaries; the driving force for this comes from the progressive decrease of the boundary energy per dislocation in the boundary, as the disorientation angle I, increases.
According to Mittemeijer [18] rays that the process of polygonization is exposed in X-ray diffraction outline by the replacement of powerfully broadened reflection, observed after the plastic deformation, by a sequence of neighbouring separate spots, observed upon succeeding annealing.
Apart from the grain boundaries, where several dislocations pile up after having moved through the core grain along preferential crystal slip planes, the problem of the line defects deserves a simulation model that extends some relevant concepts of the dislocation science: are known in solid state physics phenomena like dislocation climb and jog, polygonization structures and so on.
