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
Recrystallization mechanisms during friction stir welding/processing of aluminum alloys
TL;DR: In this article, the applicability of hot working of metals and alloys is reviewed in the context of their applicability to friction stir welding (FSW) and friction stir processing (FSP) and two of these models are used to interpret microstructure and microtexture data for two aluminum alloys subjected to FSP.
Journal ArticleDOI
Microstructure evolution during FSW/FSP of high strength aluminum alloys
TL;DR: In this paper, the microstructure evolutions during friction stir welding (FSW)/FSP has been revealed, including dDRX, grain growth, dislocation introduction, dynamic recovery (DRV), and cDRX.
Journal ArticleDOI
Friction stir processing of large-area bulk UFG aluminum alloys
TL;DR: In this article, friction stir processing (FSP) was used to refine the grain size in commercial 7075 Al to a sub-micrometer scale (∼250 nm) and the resulting microstructural characteristics were studied.
Journal ArticleDOI
Grain refinement of aluminum alloys by friction stir processing
TL;DR: In this paper, the authors investigated the structure characteristics of the processed materials and found that the nanocrystalline structures formed in the sample processed with the highest cooling rate consist of high-angle grain boundaries, and are free of dislocation cell structures.
