“…[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.

“…Some claim that f111gh110i nuclei form in the most high strained f111gh110i regions 16) and f111gh112i new grains recrystallize from f111gh112i deformed matrix, 17) while others consider that the recrystallized f111gh110i are formed in deformed f111gh112i regions and f111gh112i new grains recrystallize from f111gh110i deformed matrix. 18,19) Our experiment shows that when the initial cold rolling texture has high f111gh110i intensity, the recrystallization texture will have high f111gh112i intensity (in the case of intermediate annealing). On contrary, when the initial texture consists of high intensity f111gh112i component, the recrystallization texture will have high intensity at f111gh110i (in the case of final annealing).…”

The recrystallization behaviors of Fe15Cr ODS ferritic steels underwent two different processing routes were compared; (a) 1st 70% cold rolling + intermediate annealing, (b) 1st 70% cold rolling + intermediate annealing at 1100°C to make a recrystallization structure +2nd 70% cold rolling + final annealing. Hardness and texture changes during rolling and isochronal annealing were investigated. Results show that the recrystallization temperature of 70% cold rolled specimen is 950°C and the recrystallization texture is f111gh112i. On the contrary, in the case of specimen which was cold rolled for two times, the recrystallization temperature increases to 1100°C, and the recrystallization texture changes to f111gh110i. These changes are ascribed to the different routes of crystalline rotation during 1st and 2nd cold rolling, which produce different cold rolling texture. Higher f100gh110i content induced by 2nd cold rolling after intermediate recrystallization which has low stored energy increases the recrystallization temperature. And the difference in texture intensity along £ fibre after 1st and 2nd cold rolling results in different recrystallization texture.

“…For the 0.5Cu sample, the η oriented grains (including Goss oriented grains) nucleated at shear bands in {111}<112> deformed matrices at the beginning of recrystallization. Σ19 grain boundaries with high migration rate can form between the nucleated Goss oriented grains and the deformed matrices, which can favor the growth of Goss oriented grains [31][32][33]. Moreover, the dominant texture in the surface of the warm-rolled 0.5Cu sample was Goss texture.…”

Sheets of Fe-6.5 wt. % Si and Fe-6.5 wt. % Si-0.5 wt. % Cu with the thickness of 0.3 mm have been produced by hot and warm rolling. The microstructure, texture evolution and magnetic properties of the two alloys were investigated. It was found that the addition of 0.5 wt. % Cu promoted the formation of shear bands during warm rolling, and enhanced the {110}<001> texture at surface layer and {111}<112> texture in the middle layer. After annealing treatment, a strong η fiber texture with a peak at {110}<001> was formed in the Fe-6.5 wt. % Si-0.5 wt. % Cu sample, while the Fe-6.5 wt. % Si sample was characterized by complex γ, η and λ fibers. The formation of dominating η fiber in the annealed Fe-6.5 wt. % Si-0.5 wt. % Cu sample is attributed to the shear bands formed in {111}<112> oriented grains. These shear bands in {111}<112> oriented grains acted as the nucleation sites of η oriented grains and promoted the growth of Goss oriented grains. The presence of strong η fiber with a peak at Goss in Fe-6.5 wt. % Si-0.5 wt. % Cu sample was the cause for the higher magnetic induction observed for this sample than for the Fe-6.5 wt. % Si sample.
