Enhanced formability and hardness of AA2195-T6 during electromagnetic forming

Yanye Jin et al.

Summary: This study investigated the deformation behavior, strengthening effect, and microstructure changes of AA2195 aluminum alloy sheets treated by artificial aging and subjected to electromagnetic forming. The results showed that hardness of the conical workpiece increased with increased strain during electromagnetic bulging, along with more uniform grain distribution, higher dislocation density, and low-angle grain boundaries. The study demonstrated the feasibility of forming ultra-high-strength aluminum alloys at room temperature using electromagnetic forming technology.

Formability enhancement of 5052 aluminium alloy sheet in electromagnetic impaction forming

Fei Feng et al.

Summary: Electromagnetic impaction forming altered the formability of 5052 aluminium alloy sheets, particularly with the consideration of bilinear strain paths and continuous non-linear strain paths, increasing its formability. The conventional QS-FLC is no longer suitable for evaluating the formability of electromagnetic impaction forming.

Formability of AA 2219-O sheet under quasi-static, electromagnetic dynamic, and mechanical dynamic tensile loadings

Hongliang Su et al.

Summary: The study qualitatively categorized and illustrated the mechanisms by which electromagnetic forming improves the formability of metals. Electromagnetic dynamic loading significantly increased the forming limit of AA 2219-O sheet compared to quasi-static loading, with a marginal improvement over mechanical dynamic loading. The deformation conditions, strain rate dependency, and inertial effects played key roles in the formability enhancement in electromagnetic and mechanical dynamic loadings.

Fracture behavior of 7075-T6 aluminum alloy under electromagnetic forming and traditional stamping

Ziqin Yan et al.

Summary: This study investigated the electromagnetic forming process of 7075-T6 aluminum alloy and compared it with quasi-static stamping. Through finite element models and the Johnson-Cook model, it was found that the fracture energy of electromagnetic forming is three times that of traditional stamping, and high strain rate is the main factor affecting the material's fracture strain.
