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.
Journal ArticleDOI
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.
Journal ArticleDOI
Friction stir processing: a novel technique for fabrication of surface composite
TL;DR: In this article, a surface modifying technique, friction stir processing (FSP), has been developed for fabrication of surface composite, and the surface composites have excellent bonding with the aluminum alloy substrate.
Journal ArticleDOI
High Strain Rate Superplasticity in a Friction Stir Processed 7075 Al Alloy
TL;DR: In this article, the authors reported the first results using friction stir processing (FSP) for aluminum alloys and showed that FSP of a commercial 7075 Al alloy resulted in significant enhancement of superplastic properties.
Journal ArticleDOI
Low-temperature superplasticity in nanostructured nickel and metal alloys
TL;DR: In this article, the authors present observations of low-temperature superplasticity in nanocrystalline nickel, 1420-Al, and Ni3Al, which is the lowest normalized super-plastic temperature reported for any crystalline material.
