“…It can thus be assumed that in such a case, deformation will tend to produce a strong heterogeneous sub-structure, due to possible different re-orientation senses within a given grain. These properties of D-Cube and Goss orientations are consistent with previous experimental results obtained on single crystals [9][10][11][12]. Indeed, single crystals of D-Cube orientation were shown to keep their initial orientation even after 70% of cold reduction [9][10][11]; and the resulting microstructure was composed of very homogeneous and planar dislocation arrays [10].…”

Texture formation through strain induced boundary migration (SIBM) was investigated. Temper rolling reduction before final annealing for SIBM was varied between 0 and 26% and grain sizes and textures were measured using EBSD. In the specimen which was temper rolled to 5%, in which grain growth by SIBM occurred most efficiently, a strong Goss component (which was a minor component after rolling), developed during annealing. From the EBSD image quality analysis, it was found that stored energy increased significantly in the Goss component with strain (from 5 to 9 %), whereas it was always relatively small in the D-Cube component ({001}<110>), compared to Goss and g-fibre components. Based on these results, a mechanism of grain growth by SIBM was suggested. Texture evolution during annealing could thus be explained by the hypothesis, speculated from the analysis of orientation stability, that D-Cube grains are associated with more homogeneous dislocations distributions than Goss grains, in which the co-existence of high and low dislocation density zones could favour grain growth by SIBM.

“…(2) Wada et al [12] observed the rearrangement of the dislocations during the recovery of the cold rolled {100}<011> single crystal and they periodically formed a systematic network of {211} dislocations. When a transverse deformation is introduced to the dislocation geometry, it is easily understand to create the highly strained structure which promote complex crystal rotation expressed with eqs.…”

Heavily cold rolled BCC steel has been indicated to generate {411}<148> recrystallisation texture and its family orientations which might be represented as {h,1,1}<1/h,1,2>. As a-fibre structure, or RD//<011> texture is significantly developed during the cold rolling, it is naturally speculated to be the recrystallisation site of {h,1,1}<1/h,1,2> fibre. The present paper prompts to demonstrate the recrystallisation procedure by utilising EBSP-OIM analysis. The first demonstration was carried out with OIM analysis on partially recrystallised cold rolled steel. At the stage of 50% recrystallisation, only ND//<111> texture has appeared for the recrystallised area. {100}<011> - {211}<011> a-fibre remains as deformed structure, and several {h,1,1}<1/h,1,2> grains could be found at the grain boundaries. Therefore, a bi-crystal of {100}<011> was employed to simulate the irregular deformation at the grain boundary. After cold rolling, a warp toward the grain boundary was observed. Although the interior of the {100}<011> single crystal was hardly recrystallised, sharp {411}<148> texture was created along the grain boundary. In order to confirm the phenomenon, another experiment was carried out that a cold rolled {100}<011> single crystal was bent along the rolling direction and annealed. Very sharp {411}<148> recrystallisation texture was formed again at the bent perimeter. These experimental results lead us to conclude that the irregular strain was sufficiently piled at the grain boundary after the heavy deformation and generates {h,1,1}<1/h,1,2> texture. On {100} pole figures, the recrystallisation textures were equivalently scattered around three <100> poles, therefore the rotation relationship around <111> axes with the original orientation was suggested.

“…As can be seen from these figures, the distribution of rotation axes of the W crystal is remarkably different from that of the Ta crystal. However, it is to be noted that the almost random distribution of the rotation axes in the Ta crystal is similar to the result observed in 3% Si-Fe crystals (8) . (2) Artificial recrystallization In the same manner as previously reported (13), an artificial recrystallization technique was employed so as to obtain recrystallized grains originating from the indentations of the Vickers hardness impressed on the rolling plane of the crystals rolled 60%.…”
