“…14) • Nucleation may take place by intra-granular subgrain growth within the dense structure of the deformed gfibre grains. This mechanism was originally proposed more than thirty years ago 2,15) and has been substantiated by more recent works employing the modern techniques of SEM/EBSP (e.g. Refs.…”

“…Secondly, substructure density and work hardening are not constant throughout the cold worked matrix but vary in a systematic manner depending on the local orientation. 2) During annealing, the regions of dense substructure are those that recrystallise first 3) while the softer deformed grains remain behind. It is noticeable in Fig.…”

Evidence relating to mechanisms of recrystallisation and associated texture evolution in low carbon steels is briefly reviewed and some new observations are presented. These viewpoints are taken as the starting point for development of a computer model that can be used to predict the effects of steel chemistry and process parameters on the grain structures and textures of titanium-stabilised interstitial-free steel sheets. The model utilises physical principles as far as possible and combines these with empirical descriptions where necessary, fitting these with the aid of experimental data. Assumptions made in the model are clearly described.

“…[2,[25][26][27][28][29] According to Every and Hatherly, [29] who studied texture evolution during recrystallization in a warm-rolled low-carbon steel, preferential nucleation of h111i// ND-oriented grains is due to a higher stored energy in the deformed microstructure of this crystallographic orientation. Significant effects of the difference in the stored energy between regions having different orientations on recovery and recrystallization in rolled steels have also been reported by other researchers.…”

The evolution of the microstructure and texture during annealing of a modified ferritic/martensitic 9Cr-1Mo steel compressed by dynamic plastic deformation (DPD) to a strain of 2.3 has been investigated using transmission electron microscopy and electron backscatter diffraction. It is found that the duplex h111i + h100i fiber texture formed by DPD is transformed during annealing to a dominant h111i fiber texture, and that crystallites of the h111i component have an advantage during both nucleation and growth. Detailed characterization of the microstructural morphology, and estimation of the stored energies in h111i-and h100i-oriented regions in deformed and annealed samples, as well as investigations of the growth of recrystallizing grains, are used to analyze the annealing behavior. It is concluded that recrystallization in the given material occurs by a combination of oriented nucleation and oriented growth.

“…taciones dadas por diferentes autores (5) en las que se proponen que los primeros granos deformados que son consumidos al inicio de la recristalización pertenecen a la Fibra γ, mientras que aquellos que persisten en el estado deformado tienen orientaciones cercanas a la Fibra α. La razón de una mayor rapidez en la nucleación asociada a las orientaciones {111} va ligada a un mayor nivel de la energía almacenada en estas zonas durante la deformación en frío (6). Estos comportamientos corresponden a un mecanismo de nucleación orientada.…”

En el presente trabajo, se ha realizado un análisis de la evolución de la textura de recristalización desarrollada en un acero deformado en frío, con un contenido ultrabajo en carbono, 0.0033%, al ser recocido a diferentes temperaturas. Los cambios observados se han contrastado con los dos mecanismos propuestos en bibliografía para interpretar la formación de las texturas de recristalización: nucleación orientada y crecimiento selectivo.Palabras clave: Acero ultra bajo en carbono, recocido continuo, recristalización, textura. Texture evolution in cold-rolled steel during continuous annealingIn the present work the recrystallization texture evolution in a cold rolled ultra-low carbon steel, 0.0033%, after annealing at different temperatures has been analysed. The results have been discused in terms of the mechanisms reported in the literature to explain the recrystalization texture development, oriented nucleation and selective growth.
