“…It was calculated that the frequencies of the high‐energy boundaries (≈20°–45°) with high mobility surrounding the growing {110}<001> and {210}<001> grains were 86.95% and 82.32%, respectively, which are far higher than the frequencies of the low‐mobility boundaries (<20° and >45°). [ 33–37 ] Thus, they became the predominant textures of specimen A as a result of the high‐energy boundaries (see Figure 7c,d). In addition, the low‐index {hk0} plane with low surface energy contributed to the further development of {110}<001> and {210}<001> grains in the ultrathin sheet, [ 38 ] as shown in Figure 4a,e,i.…”

Herein, four kinds of initial Goss textures with different deviation angles (0°, 5°, 10°, and 15°) are obtained by controlling the included angles between the longitudinal directions of rectangular cutting specimens and the initial rolling direction of the raw material. Then, 0.05 mm thick grain‐oriented silicon steels are fabricated by cold rolling and primary recrystallization annealing. Effects of initial textures on the microstructure and texture evolutions and magnetic properties are investigated in detail. Compared with sharp {111}<112> in the cold rolling sheet with initial exact Goss, the deviated Goss favors the formation of strong {111}<112> + weak {h11}<1/h 1 2> textures. After annealing, sharp {210}<001> + medium {110}<001> textures develop as a result of the small initial deviation, while larger initial deviations contribute to the {310}<001> texture. In addition, the average grain sizes are also related to recrystallization textures. Consequently, the distinct recrystallization microstructures and textures result in the differences of magnetic properties.

“…in grain oriented electrical steels. 6) Among the three orientations aligning < 001 > perpendicular to the plane normal explained above, the rotated cube has been recognized as an orientation difficult to be obtained in a recrystallization process, 7) since it shows a lower stored energy during a conventional cold rolling than the other orientations. [8][9][10] Therefore, only limited methods, such as a vacuum annealing 11) or a dynamic compression with a very low strain rate, 12) could successfully obtain the rotated cube texture.…”

Extraordinarily strong recrystallization texture components near rotated cube ({100} < 011 >) developed in a low carbon steel processed with a severe cold rolling at 99.8% reduction followed by an annealing at 550°C or more. The rotated cube orientation is beneficial for magnetic applications, while it has been recognized as an orientation difficult to recrystallize. Unlike the conventional 90% cold rolling sample, the 99.8% cold rolling sample showed an unusually strong α fiber deformation texture and a fine lamellar structure understood from previous work to be generated via grain subdivision. In addition, texture analysis of a partially recrystallized sample at lower temperature anneal of 450°C revealed that the {100} < 0 7 10 > oriented grains recrystallized discontinuously from near the domain boundaries in the 99.8% cold rolled sample, while the {100} < 011 > oriented grains were likely to recrystallize continuously. Kernel average misorientation analysis of EBSD data suggested that the {100} < 011 > oriented grains underwent a faster recovery than the other α fiber orientations, resulting in a fast nucleation and growing toward the deformed matrix. Since this oriented nucleation of {100} < 011 > oriented grains was not observed in 99.8% cold rolled pure iron and 99.2% cold rolled interstitial free steel, solute carbons in the steel would play a significant role for the selective and fast recovery of the {100} < 011 > oriented grains during the annealing process.

“…Metal alloy fabrication or structure manufacturing processes, including rolling, extrusion, mechanical grinding, and machining generally subjects high shear deformation to the surface region of aluminium products which brings about various surface roughness profiles on the surface features [1][2][3][4][5]. Each cold rolling reduction deformation (CRRD) technique such as conventional cold rolling, reversing cold rolling, and twin roll casting (TRC) results in significantly different depth mapping characteristics as well as surface roughness on the surface of cold-rolled aluminium alloys [6][7][8][9][10].…”

Utilization of aluminum alloys in the automotive industry takes a crucial role in recent years due to their excellent properties such as corrosion resistance and light weight. 3003 and 8006 aluminum alloys have been particularly used as a heat exchanger compartment due to their corrosion resistance feature which has a perfect match for a heat exchanger fin stocks and a destructive salty environment in this car's part. In the present work, an effect of cold rolling reduction (CRR) rate on the corrosion twin-roll cast 8006 aluminium alloys was investigated. Firstly, the aluminium alloy was submitted to twin-roll casting process to achieve 8.5 mm thickness sheet. Then, homogenization annealing was applied between 550 °C and 600 °C. Subsequently, two cold rolling routes were subjected at different CRR rates of 94% and 98%, respectively. Finally, the aluminium sheets were annealed between 400 °C and 450 °C for 60 min. in a furnace for electrochemical corrosion tests. Electrochemical corrosion tests were performed in 1 M NaCl and H2O2 solution, and open circuit potential and polarization curves were successfully achieved. The surface features of the specimens before and after corrosion tests were assessed using stereomicroscopy and 3D profilometer. Based on the results, an increase in the various CRR rates depending on cold rolling route applied decreases the corrosion resistance of the twin-roll cast 8006 aluminum alloys. Thus, they could be very versatile materials for heat exchanger fin stock materials.
