Abstract Scope |
AA6061-T6 plates were joined together via a high velocity riveting technique with an aluminum alloy rivet at room temperature. Utilizing a powder actuated system to accelerate a striker, a metallurgical joint was formed at the interface of the plates upon impact. The dynamic behavior of aluminum at high strain rates coupled with high temperatures and pressures experienced at the bond interface produced a microstructure of recrystallized grains and sizes in the sub-micron scale and was characterized using transmission electron microscope. Interfaces were also imaged using x-ray tomography which showed a continuous weld throughout the circumference of the joint. This new riveting technique produced favorable lap shear performance compared to flow-drill screw or clinch riveted joints of comparable material combinations. By creating a joint using aluminum rivets, the recyclability challenges are addressed and create a pathway for energy conscious manufacturing pipelines that promote energy reductions for the automotive and aerospace industries. |
