Can friction-based processes be used to reprocess or manufacture materials?


Frequently asked questions

Friction hydro pillar processing, friction surfacing and friction stir processing can all be used to reprocess or manufacture materials.

Changing a material from a cast to a wrought state or producing a novel material containing a particulate (as in a metal matrix composite) are examples of materials reprocessing and materials manufacture that can be achieved efficiently using the above friction-based techniques.

At present, there is strong interest in the use of friction stir processing to develop fine equiaxed grain structures in a variety of alloys including Al, Ti, Mg and Cu. This improves mechanical properties, and also formability. In some cases, it can make alloys suitable for superplastic forming.
