Friction Stir Welding and Processing
Rajiv S. Mishra,Zongyi Ma +1 more
TL;DR: Friction stir welding (FSW) is a relatively new solid-state joining process that is used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding as discussed by the authors.

Friction stir welding of aluminium alloys
TL;DR: A comprehensive body of knowledge has built up with respect to the friction stir welding (FSW) of aluminium alloys since the technique was invented in 1991 is reviewed in this article, including thermal history and metal flow, before discussing how process parameters affect the weld microstructure and the likelihood of entraining defects.

Effect of friction stir welding parameters on the microstructure and mechanical properties of the dissimilar Al-Cu joints
TL;DR: In this paper, the effect of welding parameters on surface morphology, interface microstructure and mechanical properties of 1060 aluminum alloy and commercially pure copper butted joints was investigated. Butt joints were produced by friction stir welding (FSW), and the results revealed that sound defect free joints could be obtained under larger pin offsets when the hard Cu plate was fixed at the advancing side.

Friction stir welding of dissimilar materials between AA6061 and AA7075 Al alloys effects of process parameters
TL;DR: In this paper, the effects of materials position and welding speed on the material flow, microstructure, microhardness distribution and tensile property of the joints were investigated, and it was revealed that the material mixing is much more effective when AA6061 alloy was located on the advancing side and multiple vortexes centers formed vertically in the nugget.

Microstructural investigation of friction stir welded 7050-T651 aluminium
TL;DR: In this paper, the grain structure, dislocation density and second phase particles in various regions including the dynamically recrystallized zone (DXZ), thermo-mechanically affected zone (TMAZ), and heat-affected zone (HAZ) of a friction stir weld aluminum alloy 7050-T651 were investigated and compared with the unaffected base metal.

Properties of friction-stir-welded 7075 T651 aluminum
TL;DR: Friction stir welding (FSW) was used to weld 7075 T651 aluminum, an alloy considered essentially unweldable by fusion processes as discussed by the authors, which exposed the alloy to a short time, high-temperature spike, while introducing extensive localized deformation.
