What is friction stir processing?

   

Friction stir processing (FSP) is used to transform a heterogeneous microstructure to a more homogeneous, refined microstructure. There are several possible methods available which can be applied to a variety of material shapes and sizes.

In many cases, the re-processed areas have superior strength and formability than the parent material, e.g. aluminium castings can be processed to consolidate voids, or extrusions can be improved in highly stressed areas. In combination with superplastic forming, FSP offers the potential to form complex-shaped parts at higher strain rates and in section thicknesses not possible using conventional superplastic processing.
