عنوان انگلیسی Experimental and Numerical Investigation of the Formability of Cross and Accumulative Roll Bonded 1050 Aluminum Alloy Sheets in Single Point Incremental Forming Process
چکیده انگلیسی مقاله As one of the methods of Severe Plastic Deformation (SPD), the Accumulative Roll-Bonding (ARB) process leads to the production of high-strength metal sheets and fine-grained structures. In this paper, the Single Point Incremental Forming (SPIF) of Al1050 sheets, processed by the ARB and CARB (Cross-Accumulative Roll-Bonding), is experimentally and numerically investigated. The forming force, thickness distribution, and forming depth in both cases (ARB and CARB) are all determined in this research. The result shows that the formability of CARB samples is higher than ARB samples. Furthermore, the formability of both ARB and Al1050 annealed samples are equal in the initial pass. In addition, the samples’ strain is enhanced by increasing the number of rolling passes, and as a result, the formability scales down. The results obtained using the dynamometer reveals that the vertical forming force extent in the CARB samples is higher than the rest of the samples.
