The Influence of Material Position towards the Bending Strength of the 4 Pass AA1050/AA6082 and AA6082/AA1050 FSPed Joints

Abstract

This paper reports on the influence of material position towards the bending strength of the 4 pass AA1050/AA6082 and AA6082/AA1050 FSPed joints. FSW approach was utilized to create dissimilar joints using two dissimilar plates. After that, the created dissimilar joints were put through a multi-pass friction stir processing. The microstructural analysis results revealed that the 4P 6082/1050 joint had substantially finer grains than the 4P 1050/6082 joint. The 4P 1050/6082 joint yielded the highest ultimate tensile strength when compared to that of the 4P 6082/1050 joint. The Vickers microhardness of 1050/6082 FSPed joints was found to be increased towards the AA6082, while 6082/1050 FSPed joints decreased towards AA1050. The bending strength analysis showed that there was no obvious trend in flexural strength.
