The study evaluated the influence of material positioning on the metallurgical and mechanical properties of Cu/Al and Al/Cu MFSCB joints with the use of Zn as interlayer. The results showed that material positioning significantly affected the quality of the joints, with a significant improvement in the performance of the joint when pure copper was placed on top of AA5083 in condition #1.
The influence of material positioning during modified friction stir clinching brazing (MFSCB) of Cu/Al (condition #1) and Al/Cu (condition #2) with the use of Zn as interlayer on metallurgical and mechanical properties was assessed. It was found that properties of MFSCB joints are markedly affected by the positioning of the materials. Further, results demonstrated that in condition #1, when pure Cu was placed on top of the AA5083, a sound weld without any crack at the brazed zone was created and the fracture load of the joint during peel test appreciably improved (approximately 30%) in comparison with condition #2.
