Electron backscattered diffraction method in the analysis of deformed   steel structures
  The structure of low-carbon steel after twist extrusion is tested with using electron backscattered diffraction. It has been shown that warm twist extrusion results in grain refinement with conservation of a substantial part of high-angle boundaries, smearing of the texture, more homogeneous distribution of grains and development of the dynamic recrystallization processes.
