Microstructural aspects and mechanical properties of friction stir welded AA2024-T3 aluminium alloy sheet

Influence of process parameters on mechanical performance and bonding area of AA2024/carbon-fiber-reinforced poly(phenylene sulfide) friction spot single lap joints

“…However, the weldability of the 2xxx series of aluminum alloys including AA2024 by traditional fusion welding technologies is limited [17]. Advanced solid state welding techniques such as friction stir welding [18] and friction spot welding [19] are used to join the aluminum 2xxx series. Table 1 lists the nominal chemical composition of the AA2024-T3 alloy used in this work, which was determined by chemical analysis.…”

The microstructural evolution of friction stir welded AA6082-T6 aluminum alloy during cyclic deformation

“…Refs [6][7][8][9][10]. In general, FSW slightly reduces yield strength, ultimate tensile strength, tensile elongation to failure, and fatigue strength compared to the parent material [11][12][13][14][15]. In the specific case of low-cycle fatigue, Feng et al [16] observed that cracks initiate at the specimen surface in the NG zone during studying the cyclic-strain behaviour of 6061Al alloy.…”

Effect of tool pin profile on microstructure and mechanical properties of friction stir welded pure copper joints

“…Although FSW has been investigated extensively in the case of aluminum alloys [8][9][10] and magnesium alloys [11,12], there are only a few studies investigating FSW of pure copper and its alloys [13][14][15][16]. Xie et al [14] investigated the effect of tool rotation rate on microstructure and properties of friction stir welded (FSWed) copper joints at constant traverse speed.…”
