Abstract
Equal channel angular pressing is one of the most efficient techniques among severe plastic deformation methods that enhances the mechanical properties of polycrystalline metals by refining subjected grains. In this article, equal channel multi-angular pressing was conducted on Al5754 strips. At the first step, finite element analysis was applied to evaluate the possible routes (A and C). The initial analysis showed that the route C was better in strain homogeneity compared with route A. Thus, the route C was considered for further investigations. Then, the effects of the die geometrical parameters on the created equivalent plastic strain (PEEQ) and process force were investigated by FEM. The results showed that the die channel angle (Φ2) was the most effective parameter on both PEEQ and process force, while the die corner angle (ψ1) had the least effect on both objectives.
