Abstract:The AA6082–AA8011 friction stir-welded joints were subjected to submerged multiple pass friction stir processing to evaluate the microstructure and mechanical properties of the joints. A maximum of four submerged friction stir processed passes were used in this study. All the specimens were extracted from three different joint positions (start, middle and end). The tests conducted included microstructural analysis, tensile tests, hardness and fracture surface morphology of the post-tensile specimens, were perf… Show more
“…The increase in the number of FSP passes increased the fatigue life of the joint." A recent similar study was also performed by Mabuwa and Msomi [88]. However, the 4-pass technique was performed under cold water.…”

Friction stir processing (FSP) is a microstructural modifying technique that uses the same principles as the friction stir welding technique. FSP technique can be employed on the same surface repeatedly as desiredand this repetition is called multi-pass friction stir processing (MFSP). The recent developments have shown that MFSP technique is very useful towards uniform dispersion of reinforcement particles during fabrication of surface composites. Some studies have also demonstrated that MFSP technique can be employed on welded joints as a way of improving the mechanical properties of the welded joints. This paper reports on the progress made in using the multi-pass friction stir processing (MFSP) technique in producing aluminium-based surface composites. It further looks at the progress made in using the MFSP on aluminium-based welded joints. An effort is made to identify the gap that requires some exploration for the better utilization and understanding of this technique
