Electron backscattered diffraction method in the analysis of deformed steel structures

TL;DR

This paper uses electron backscattered diffraction to analyze how low-carbon steel's microstructure changes after warm twist extrusion, revealing grain refinement, texture smearing, and recrystallization.

Contribution

It demonstrates the effectiveness of EBSD in characterizing microstructural evolution in steel subjected to twist extrusion.

Findings

Grain refinement occurs after twist extrusion.

High-angle boundaries are largely conserved.

Dynamic recrystallization develops during processing.

Abstract

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.
