Microstructure-property relation and evolution in friction stir welding of naturally aged 6063 aluminium alloy

Microstructure and texture evolution of friction stir welded dissimilar aluminum alloys: AA2024 and AA6061

“…The formation of shear textures such as {031}_213_, {111}_112_,{001}_110_, {111}_110_ components during FSW is due to the severe shear strain produced on the retreating side. This is consistent with the literature [4,10,11]. Some main shear components including {111}_110_ and {111}_112_ are described by a _-fibre texture, which runs from the Fig.…”

“…For this reason, the aluminium alloys which are practically unweldable or difficult to be welded using fusion joining techniques are weldable with almost no defects by friction stir welding [1,4,[7][8][9].Significant differences may be expected in terms of the microstructure and crystallographic texture on both the advancing and retreating sides of friction stir welded joints especially for dissimilar ones [1]. In general, the microstructure of FSW joints is divided into four regions: stirred zone (SZ), thermo mechanically affected zone (TMAZ), heat affected zone (HAZ), and base metal(BM).A number of researchers have investigated the microstructure and texture evolutions of similar and dissimilar heat treatable aluminium joints [4,[10][11][12][13]. Xu et al [10] reported the microstructure and texture evolutions of AA7005 aluminium alloy under FSW pro-cess.…”

“…The high angle grain boundaries (HAGBs) distribution were the most significant in the stirred zone followed by the retreating side and then on the advancing side. Imam et al [11] studied the microstructure and texture evolution during FSW of 6063 aluminium alloy. They found that the B/B texture component was dominated at the top of the weld joint, while the {111}_112_ components of A fibre and C component of B fibre were found at the bottom of the weld joint.…”

The Microstructure, Texture and Mechanical Properties of Friction Stir Welded Aluminum Alloy

“…Numerous published reports [4][5][6][7][8][9][10][11][12][13] indicate that there is strong microstructural and textural evolution in similar and dissimilar heat treatable aluminum joints that are characterized by the thermal and deformation histories. These authors evidenced the occurrence of a recrystallization concomitant with the texture change and both contributed to the grain refinement of a stirred zone down to the sub-micrometer level.…”

Influence of artificial aging on the electrochemical properties of the aluminium AA 6063 alloy

“…These alloys find application in the artificial aging condition, which makes it possible to obtain excellent mechanical properties. [1][2][3][4][5][6][7][8][9][10][11][12] The physical properties exhibited by aluminium alloys are significantly influenced by the treatment of the sample. In all the above-mentioned applications, alloys are prone to corrode, while also exposed to severe atmospheric environments.…”
