There is evidence that the unique microstructure is formed by rotational dynamic recrystallization.
The formation of the ultrafine and equiaxed grains in the transformed bands could be attributed to the rotational dynamic recrystallization mechanism.
Under particular conditions, grains as small as several nanometers can be generated in the vicinity of these bands, through the activation of rotational dynamic recrystallization.
Finally, the grain refinement in an adiabatic shear band in the 200 series Fe Cr Ni austenitic stainless steel is described as a consequence of the rotational dynamic recrystallization.
The dynamic recrystallization was accompanied by the formation of disclinations, deformation bands, low-angle, and high-angle boundaries, i.e., rotational deformation modes developed.
It is purified by recrystallization and sublimation.
Rotational speed is crucial for velocity.
Other processes are performed below the recrystallization temperature.
(4) Fluid solutions can enhance deformation, creep, and recrystallization.
