Abstract
In engineering applications, such as automobile, marine, aerospace, and railway, lightweight alloys of aluminum (Al) and magnesium (Mg) ensure design fitness for fuel economy, better efficiency, and overall cost reduction. Friction stir welding (FSW) for joining dissimilar materials has been considered better than the conventional fusion welding process because of metallurgical concerns. In this study, dissimilar joints were made between the Aluminium (Al) AA6061-T6, Magnesium (Mg) AZ31-B, with addition of SiC –Nano partical combinations based on the varying process parameters. The dissimilar joints prepared by the FSW process were further characterized by tensile testing, hardness testing, fracture testing. The results of the properties were supported by fracture analysis by scanning electron microscopy (SEM) observations. In this study, tensile testing, micro-hardness, and fracture behavior of the joints of Al and Mg alloys manufactured by the FSW process is considered for evaluation.
