“…The precipitate evolution affects the hardness of every region and the coarsening of Al-Cu precipitate decreased the hardness in weld[18 -20]. As AA 2219 and AA 2014 are high strength alloys with superior mechanical, metallurgical and corrosion properties, a lot of work have been carried out in similar welding of these two materials individually for numerous implementations [2,19,21,31]. However, no research has been tried on dissimilar welding of AA2219 and AA2014 which has a higher potential application in aerospace sector; especially in the counterpart connecting the cryogenic engine fuel tank and the inter-stage of space vehicles.…”

In this study, Friction stir welding (FSW) is carried out on dissimilar aluminium alloys AA2219 and AA2014 using L16 orthogonal array based on Taguchi Mixed Factorial Design (TMFD) under four process variables: traverse speed, rotational speed, tilt angle and tool profile and the effects of FSW parameters on responses (Tensile Strength, Yield Strength and Elongation) are analyzed using single response optimization and multi-objective Taguchi coupled with Grey Relational Analysis. A parameter setting of A4B4C2D1 is found to be optimal demonstrating 86% of parent material strength. Further, mechanical and metallurgical studies were carried out using SEM, EDAX and XRD analyses. From micro-hardness testing, it was observed that failure occurs at the lower hardness side in the advancing side of AA2219. SEM fractography reveals dispersion of particle which improved weld strength by regulation of coarseness and dissolvability of precipitates in the weld region. EDS point, line and elemental mapping confirmed the presence of copper particle dispersion that acts as a binder and resist void formation, and this is further confirmed by XRD analysis.

“…They concluded that tool profile, rotational speed, welding speed, and axial force has significant impact on corrosion rate. Similarly, Zhang et al 17 investigated the effect of transverse speed, plunge depth, and rotational speed on corrosion rate, yield strength, ultimate tensile strength (UTS) and elongation for AA 2024-T351 and AA 7075-T651 dissimilar alloys. They also developed a mathematical model and verified it using Analysis of Variance (ANOVA) to determine the optimum set of process parameters to maximize tensile properties and corrosion rate.…”

Friction Stir Back Extrusion (FSBE) is a new sustainable manufacturing process capable of producing fine grained lightweight tubular shapes. The objective of this work is to investigate the impact of rotational speed and feed rate on the mechanical properties, cycle time and power consumption of friction stir back extruded Mg AZ31-B tubes and determine the optimal settings. FSBE experiments and tensile tests were performed to characterize the mechanical properties of the produced tubes. The investigation is conducted utilizing Response Surface Methodology (RSM) and desirability multi-response optimization technique. Results suggest that ultimate tensile strength and toughness are impacted by both rotational speed and feed rate and are more sensitive to speed. However, both process parameters did not show a significant statistical impact on elongation. Optimal parameters for mechanical properties were identified at a rotational speed of 1767 rpm and feed rate of 102 mm/min. The optimal settings to maximize mechanical properties, minimize power consumption, and maximize productivity were 2000 rpm and 116 mm/min.
