# Recrystallization Texture Evolution in Fe–3.0 wt.% Si Hot-Rolled Silicon Steel Sheet by Quasi In Situ EBSD Analysis

## TL;DR

This study examines how the crystal structure of a specific type of steel evolves during recrystallization using electron backscatter diffraction.

## Contribution

The paper provides new insights into the texture evolution and grain nucleation mechanisms in Fe–3.0 wt.% Si steel during recrystallization.

## Key findings

- Goss texture remains stable in the surface region while α and α* textures strengthen during recrystallization.
- In the center region, α texture weakens and Goss texture intensifies during recrystallization.
- Different grain orientations nucleate and grow by consuming specific deformed matrix orientations in surface and center regions.

## Abstract

The microstructural and textural evolution in hot-rolled Fe–3.0 wt.% Si steel sheets was investigated by quasi in situ electron backscatter diffraction (EBSD) analysis. During recrystallization, the Goss texture intensity in the surface region remains essentially unchanged, whereas the α and α* textures are strengthened. In the center region, the α texture weakens, and the α* texture shows little variation, while the Goss texture becomes intensified. In the surface region, {112}<110> recrystallized grains nucleate by consuming deformed matrices with orientations near {114}<221> and {110}<112>. Recrystallized {114}<481> and {001}<210> grains consume deformed matrices near {114}<221> and Goss orientations, while Goss grains nucleate by consuming Goss-oriented deformed matrices. In the center region, {112}<110>, {114}<481>, and {001}<210> recrystallized grains nucleate and grow by consuming α and λ type deformed matrices, whereas Goss recrystallized grains preferentially consume deformed matrices with orientations of {111}<112>.
