Springback evaluation of 5052-H32 aluminum-magnesium alloy
MetadataShow full item record
Springback is one of the most common problems in sheet metal forming operation. It causes improper fit which creates serious problems during assembly of the parts. Based on material strength, a considerable elastic recovery during unloading can be observed. In the present study, the springback evaluation of 5052-H32 aluminum magnesium alloy sheets with a thickness of 1.5 mm was investigated using 60o angle V-shape die at several temperatures range of room to 300°C and strain rate range of 25-625 mm/min. Although the springback of the material was increased with increasing the temperature up to 200°C, it was decreased for all deformation speeds at 300°C. Bending force of the material was not changed with deformation speeds except for 300°C. The bending force was obtained at 625 mm/min is higher than the other deformation speeds. The best bending condition of this material was obtained at 300°C and 25 mm/min.
