“…When the figure is analysed, it can be seen that as the die angle increases, the springback decreases, which also means that as the die angle decreases, the tension increases, and accordingly, springback also increases. This case can be explained by the increase of bending moment in the bending zone, which is compatible with the findings of other studies [15]. Several researchers [16–18] have stated that the springback of sheet material is associated with tangential stresses.…”

Springback plays a key role in the geometrical and dimensional integrity of the product obtained in metal forming. This study investigated the formability of high-strength complex phase CP800 sheet under V-bending at room temperature. The experiments were carried out on 2.5-mm-thick material using parameters of four different bending angles, three different punch radii and two different holding times. The effects of selected parameters on springback were investigated both experimentally and via finite element analysis (FEA). As a result of the study, it was determined that the amount of springback decreased as the die angle (α) increased and increased as the punch radius (r) increased, and that the effect of the holding time remained limited. In addition, the damage was observed in the bending samples obtained under experimental conditions of α = 60°and r = 2 mm. The experimental and simulation findings showed that the measured angles (β) were in good agreement (>95%).

“…The number of springback increases or decreases in proportion to the stress formed in the bending region. In other words, as the die angle increases, the bending moment in the bending region decreases, which reduces the springback angle, (Trzepiecinski and Lemu, 2017;Aydin and Karaaǧaç, 2019;Ma et al, 2019). In the unrolled (UR) sample, springback occurred in bending with 60° die, while spring-forward was observed in bending made with 90° and 120° die.…”

The Differential Speed Rolling (DSR) process is a severe plastic deformation method used in the production of microstructured materials with both high deformation and superior mechanical properties. This study has focused on determining the springback behavior and formability of the materials obtained by using the DSR method after the V bending process. Rolling processes were carried out at 4 different rolling speed ratios (1.0, 1.33, 1.66, and 2.0), 25% thickness reduction ratio, and 2 different rolling temperatures (room temperature and 580 °C). Then, the rolled sheet materials were bent using 3 different bending die angles (60°, 90°, 120°). As a result of this study, the greatest plastic deformation was reached at a speed ratio of 2.0 at 580 °C. Again, the lowest springback was obtained at 580 °C. As the die angle increased, the springback decreased. Springback has occurred in the bending process of all sheet materials obtained by rolling. In the bending process of the unrolled sheet material, both spring-forward and springback events were observed depending on the die angle.
