“…Although the nanoparticles are located only on the interfaces, the distance between the interfaces with nanoparticles in the final ARB cycles becomes small, so the recrystallization may originate on the interfaces, and a new grain boundary can migrate up to half of this distance, influencing the microstructure and texture in the whole volume of the sample. It should be noted that the prevalence of Copper and Dillamore texture components was also found in the Al–Al 2 O 3 composite fabricated by ARB when the volume fraction of alumina was low …”

An Al–0.05 vol% nAl2O3 (where nAl2O3 is alumina nanoparticles) composite has been fabricated using accumulative roll bonding with nanoparticle introduction. The microstructure, texture, fracture surfaces, and mechanical properties are investigated using transmission and scanning electron microscopy, electron back scatter diffraction (EBSD), microhardness measurement and tensile tests. The results show that nanoparticle introduction significantly affects the microstructure, texture, and fracture characteristics, but weakly influences the microhardness, strength, and ductility. The possible reasons for the different responses of the studied properties to nanoparticle introduction during accumulative roll bonding are discussed.

“…The initial texture of the annealed commercially pure aluminum was reported as Cube ({001} <100>) with a maximum intensity of two (2 × R ), indicating a weak texture that could be a characteristic of recrystallization . Figure shows that, contour lines are distributed without any concentration on a specific component after the 1st pass and it is only after 3 ARB passes, that Copper and Dillamore components were observed with intensities of 5.…”

“…One of the most important parameters that affects the deformation texture is the presence of a second phase. For example, in Al–Al 2 O 3 composite during ARB process, Rotated Cube was reported as the main texture, but at low percentage of Al 2 O 3 , Copper was the major texture component . It was mentioned that Al 2 O 3 particles, randomized the deformed texture in the adjacent areas and turned the texture to Rotated Cube texture.…”

In the present work, aluminum-3% brass composite sheets are produced by accumulative roll bonding (ARB) process up to nine passes at ambient temperature. Evolution of rolling texture is studied by texture measurement using X-ray diffraction method. The results show that ARB process leads to the formation of copper ({112} <111>) and Dillamore ({4 4 11} <11 11 8>) as the major texture components. The intensity of copper and Dillamore components enhances to values as high as 19 times that of random with increasing number of passes to 9. It is observed that the 5th pass is a transition in development of the texture components, after which the intensities undergo a drop. The textures are comparable to ARB process of high purity aluminum, indicating that the addition of 3% brass particles do not cause any significant change in the deformation behavior. Electron backscatter diffraction (EBSD) technique is used to examine the microstructure; the results reveal formation of ultrafine grains (UFG), starting in the 3rd pass and covers the entire structure after the 5th pass. The major mechanisms involved are identified as rotation of the sub-grains, as well as grain boundary migration.

“…The ARB has been usually performed under high friction condition, which affected microstructure evolution as well as texture development . It was found that microstructure and texture evolution were not similar to that of conventionally rolled samples . The microstructure evolution and related mechanical properties of Al‐Mg alloys subjected to ARB process had been extensively investigated, although results of the examination of its corrosion properties are limited.…”

Influence of accumulative roll bonding (ARB) and conventional cold rolling (CR) on the mechanical and corrosion properties of AA5083 alloy sheets has been studied. Tensile tests showed significant increase in strength and a decrease in elongation after each ARB deformation and cold rolling reductions. Results of nitric acid mass loss test (NAMLT) revealed that cold rolled and ARB processed specimens were resistant toward intergranular corrosion (IGC) in as‐deformed state. However, after 7 days of sensitization at 100 and 150 °C, cold rolled material became IGC sensitive, while ARB specimens stayed IGC resistant. IGC susceptibility can be correlated with different morphology and distribution of β‐phase (Mg2Al3) precipitated during sensitization. It was found that extensive shear banding contributed a favorable distribution of β‐phase precipitates in the structure of IGC resistant ARB processed specimens. In case of IGC susceptible conventionally cold rolled specimens, large amount of β‐phase precipitated preferentially along the elongated grain boundaries. Electrochemical parameters were in a good correlation with the results of NAML tests, which in turn, confirmed the superiority of ARB multilayered structure over conventional cold rolled structure in terms of IGC susceptibility and corrosion stability.
