“…Technical difficulties in implementing the process using recommended parameters, such as high friction or high thickness reduction per pass, in a laboratory setting entail the usage of industrial-grade equipment, not readily available. On the other hand, industries were firstly interested in assessing ASR benefits on the rolling process itself, such as strip curvature, rolls service life, and rolling power [12,[94][95][96][97].…”

Asymmetric rolling is an attractive metal forming process due to its simplicity, low cost and capability to produce unique characteristics in materials. The asymmetry promoted by the process leads to a formation of a large collection of texture components and a refined structure which is capable to improve the mechanical behavior of metallic materials. The aim of this work is to present a perspective of the process and to construct the bases for future development and application of this technique. Thus, several aspects are addressed such as process methods (i.e., dissimilarity of the rolls diameters, rolls angular speed or friction conditions), the process parameters (i.e., total thickness reduction, thickness reduction per pass, peripheral speed ratio, rolling routes) and their effect on material properties, including texture and microstructure evolution, and mechanical properties. This review is focused on the experimental description of asymmetric rolling applied to aluminum alloys and steels. Although the asymmetric rolling application was mostly at a laboratory scale, there is a good perspective for its implementation in the industry. The pros and cons based on the up to date literature and authors’ experience are presented and discussed.

“…A specific study of the effect of different rolling speeds on the sheet warp was presented in ref [5]. Jaroslaw et al [6] reported that bending of the strip is caused by the different working roll diameters based on analysis using Elroll computer software. A detailed investigation into the transverse bending of a cold-rolled strip was conducted by Zhang and Dai [7][8][9].…”

Transverse bending, a common shape defect of hot-rolled strips, is generally controlled based on experience, which lacks quantitative study. This leads to some production problems such as difficult feeding and surface scratching in subsequent processes. Based on the principle of elastic mechanics, the mechanism of transverse bending in the process of uncoiling is studied and an analytical model is established. Then the relationship between transverse bending and influence factors, including the curvature radius of longitudinal bending, strip width and strip thickness, is obtained. The study indicates that the transverse bending is caused by longitudinal bending before uncoiling. And the strip width and the curvature radius of longitudinal bending have a great influence on the transverse bending but the strip thickness has little influence. The transverse bending diminishes nonlinearly with the increase of curvature radius of longitudinal bending and increases nonlinearly with the increase of strip width.

“…Grain diameters of the order of one micron were reported for aluminum alloys and lead to a substantial hardening as expected from the Hall–Petch relationship. Recent publications are mostly concerned with numerical simulations or analytical modeling . The ones that are concerned with the experimental aspect give indications about the processing conditions and the mechanical properties.…”

International audienceThe mechanical behavior under uniaxial tension of Al-Mg alloy 5182 pre-deformed in conventional rolling (CR), asymmetric rolling-continuous (ASRC), and asymmetric rolling-reversed (ASRR) was investigated and modeled with a rate dependent crystal plasticity finite element method and VPSC (Visco-Plastic Self Consistent) model. M-K theory combined with Yld2000 model by Barlat et al. (Int. J. Plasticity 2003, 19, 1297) was used to predict the strain-based and stress-based formability for AA 5182 material. It was concluded that the new ASRR process has very compatible formability with improved strength compared to CR process. These merits can be directly applied for clam-shell resistant design in rigid-packaging industry
