“…Fine grained microstructures in an AA5754 aluminum alloy after asymmetric rolling and subsequent annealing are discussed in [27]. In [28], shear deformation texture and grain refinement after asymmetric rolling of aluminum are studied. Grain refinement due to recrystallization during hot rolling is considered in [29] regarding steel sheets and numerical simulations of hot rolling of an AA5083 aluminum alloy are performed in [30].…”

The microstructure evolution during cold rolling of commercial purity AA1050 aluminum is investigated through numerical simulations. A finite strain elasto-viscoplastic constitutive model is employed, where the dislocation density and average grain size are taken as variables characterizing the deformed microstructure. Grain size evolution due to dynamic recrystallization is considered and the microstructure quantities are allowed to influence the macroscopic material behavior in terms of the flow stress and deformation-rate dependence. The effects of such process parameters as rolling friction, thickness reduction in each rolling pass and amount of rolling asymmetry are discussed. The results indicate that grain refinement due to dynamic recrystallization is most significantly affected by the amount of thickness reduction in each pass and the level of rolling friction and to a lesser extent by the asymmetry of the rolling process. An increasing degree of asymmetry will, however, reduce the variations in grain size through the sheet thickness and leave the material more homogeneously recrystallized.

“…where ν is 0.33 (this is typical value for high purity Al alloys) [7,30,31] , and ρ is the dislocation density, which was estimated by [14]. Another method for calculation stored energy is apply the formula from [13] modified using the Kubin-Estrin (KE) model is:…”

“…The most common fibers are the β-fiber created by the Copper, S, and Brass textures, the α-fiber (〈110〉//ND) and the γ-fiber (〈111〉//ND). In the Face Centered Cubic (FCC) metals, the α-fiber and β-fiber components are indicative of plane strain compression, while the γ-fiber tends to appear after shear [14][15][16]. However, annealing can transform the deformation textures to recrystallization textures, like the Cube (100 〈001〉) [11,17].…”

The current as well as the future industrial market for Aluminium (Al) is huge and various research is being under work regarding the usability of Aluminium. However, during the deep drawing of Aluminium several issues can be developed and some of them are originated from the fundamental material properties. One of these factors is the material texture, which is the preferred orientation of the constituent polycrystalline Al, and the characteristic texture is affected by different rolling and annealing schedules. To investigate the material texture, symmetric and asymmetric rolling trials were performed on a commercially available Al 1050 sample. Energy-dispersive X-ray Spectroscopy (EDX), and Electron Backscatter Diffraction (EBSD) scanning has performed to determine the material composition and the crystallographic orientations of the investigated samples.
