Abstract
Electron backscatter diffraction (EBSD) analysis has been presented to investigate the microstructure and microtexture evolutions of deformed oxide scale formed on a microalloyed steel during hot rolling and accelerated cooling. Magnetite and wustite in oxide layers share a strong {0. 0. 1}and a weak {1. 1. 0} fibres texture parallel to the oxide growth. Trigonal hematite develops the {0. 0. 0. 1} basal fibre parallel to the crystallographic plane {1. 1. 1} in magnetite. Taylor factor estimates have been conducted to elucidate the microtexture evolution. The fine-grained magnetite seam adjacent to the substrate is governed by stress relief and ions vacancy diffusion mechanism.
