SEM analysis of AL6082 by adding nickel & titanium after friction stir processing

Friction-stir processing (FSP) is an emerging surface-engineering technology that can locally eliminate casting defects and refine microstructures, thereby improving strength and ductility, increase resistance to corrosion and fatigue, enhance formability, and improve other properties. FSP can also produce fine-grained microstructures through the thickness to impart super plasticity. The technology involves plunging a rapidly rotating, non-consumable tool, comprising a profiled pin and larger diameter shoulder, into the surface and then traversing the tool across the surface. Large surface areas can be traversed rapidly by using the appropriate tool design accompanied by raftering. These processes are more likely to have an influence on the design, engineering and manufacturing of passenger vehicles in future. A lot of emphasis has been placed on the manufacture of fuel-efficient vehicles, increased use of lightweight materials as well as more efficient and cost-effective processing techniques. In the present study Scanning Electron microscope results of the prepared specimen is discussed.
