| Abstract Scope |
Experimental studies have been carried out to understand the performance of high strength automotive Al-Mg-Si alloys joined by Self Piercing Riveting (SPR) technology, in terms of joint structure, mechanical properties, failure mechanism, and corrosion resistance.Four Al-Mg-Si alloys were tested under a variety of joining conditions with or without adhesives, using a C-type frame Henrob SPR equipment.Joint structures were examined by optical and electron microscopy.Lap-shear, and T-peel tests were performed to evaluate the mechanical behaviour.Immersion tests were conducted to assess the corrosion response of the joints.The addition of fresh adhesives was found to have significantly increased the joint strength. Material flow pattern and interactions between the matrix material and the rivet surface exhibited considerable impact on the joint structure and corrosion behaviour.Further examination under fatigue testing will be performed, in combination with computer simulation, will be performed to gain more comprehensive understanding of the SPR joint performance for the material. |
