Abstract Scope |
Friction stir welding (FSW) technology has recently received reasonable attention to process a wide range of materials either similar or dissimilar. In this work, the feasibility of FSW as a tool to repair surface cracks is examined, where an artificial crack made on aluminum alloy 6061-T6 plate surface is repaired by depositing nanoparticles of SiC, along with filler of same base material to fill the crack, before the repair, then the filled crack is friction stir processed. The paper investigates the impact on repaired zone microstructural aspects along with mechanical properties in terms of tensile and hardness response. For welded samples, the location of the fracture is distant from the weld zone. The addition of SiC nanoparticles showed some promise for potentially improving ductility in certain cases, but proper mixing appears essential. Scanned welded surface using SEM give abundant data to explain the mechanical results. |
