Abstract |
|
During the rolling process of pure aluminum foil, the deformation behavior of the foil is very complex. The amount of deformation has a decisive impact on the microstructure. Therefore, studying the deformation behavior of high-purity aluminum foil rolling is of great significance. In this study, high-purity aluminum foils were prepared through a multipass rolling process with different reductions of 10%, 20%, 30%, and 40%. The strengthening mechanism was elucidated by testing and observing the microstructure and mechanical properties of the samples at the optimal reduction. Furthermore, numerical simulation was conducted to refine the deformation process of pure aluminum foil during rolling, and the grain size and strain conditions were observed. The results shown that there is an indirect relationship between grain size changes and strain. Dislocation strengthening and grain refinement at a 30% reduction rate are key strengthening mechanisms for improving the strength of aluminum foil. Additionally, S-type texture, brass-type texture, and cube texture also contribute to the mechanical properties. |
