Friction-stir welding (FSW) is a solid-state joining process and is used for applications where the original metal characteristics must remain unchanged as much as possible. The process is applicable to aerospace, shipbuilding, aircraft and automotive industries. One of the key benefits of this new technology is that it allows welds to be made on alloys that cannot be easily arc welded.
More recently friction-stir processing (FSP) has been shown to alter the surface microstructure of a material via in-situ thermo mechanical processing. The FSP causes intense plastic deformation and material mixing at high strain rates, resulting in significant refinement, and redistribution of particles in the processed zone.
