“…However, a further increase in the speed to 110 mm min À1 resulted in appreciably high wear rate. This observation agreed with earlier findings by Palanivel et al [23] and Dinaharan et al [24]. The lowest wear rate at 65 mm min À1 can be ascribed to better material mixing and grain refinement at the Fig.…”

“…The same zone where the wear test was carried out. This is another confirmation that hardness is inversely proportional to wear rate as reported by some authors [24,25]. The wear rate at the three rotational speeds studied was generally lower than those of the two parent metals.…”

“…On this basis, an appropriate combination of the feed rate and the rotational speed of the tool can be said to be a significant factor for FSW control that determines the mechanical properties of the welded joint. Another significant factor affecting good mechanical strength, good material mixing and bonding in dissimilar aluminium friction stir welding is the relative positions of the alloys during the welding [18,24]. For instance, Guo et al [20] noted a better material mixing condition at the nugget zone of the weld when the softer alloy (6061) is placed on the advancing side while the harder one (7075) is kept on the retreating side during the FSW of both alloys.…”

Dissimilar friction stir welding (FSW) between 6101-T6 and 7075-T651 aluminium alloys was conducted. Three different parameters each were investigated for rotational speed and travel speed, and the effects of these parameters on the tensile behaviour, hardness and wear were evaluated. The results indicate that the ultimate tensile strength increases with an increase in the feed rate. However, the increase in rotational speed decreases the ultimate tensile values. The fractured analysis of the tensile samples shows similarities in the fractured pattern as all the samples failed at heat affected zone close to the 6101-T6 alloy. The hardness varies across the heat affected zones and nugget zone both at constant rotational speed and welding speeds. The highest resistance to wear occurred at 65 mm min À1 and 1850 rpm welding speed and rotational speed respectively while better material mixing was achieved at the nugget zone of the welds at 1250 rpm and 110 mm/min.

“…A pinless tool was used in FSP process to close the groove. The frustum pin geometry for FSW was chosen based on research by Bahrami et al, 2014a, also the pin and shoulder dimensions were selected considering design and descriptions presented by Arora et al, 2011;Bahrami et al, 2014a;Elangovan and Balasubramanian, 2008;and Padmanaban and Balasubramanian, 2009. In each experiment, the nanoparticle theoretical volume fraction (Vf) in the stir zone, calculated using the ratio of groove area to tool pin projected area, was about 16%, according to Dragatogiannis et al (2016). This parameter was kept steady under all conditions.…”

Prior to friction stir welding (FSW), silicon carbide (SiC) nanopowders were placed inside the groove on the adjacent side of magnesium sheet. In order to make a good distribution of these nanoparticles, first, friction stir processing (FSP) with a pinless tool was conducted on this side. Second, using a frustum pin tool, a combination of two travel speeds (25 and 35 mm/min) and three rotation speeds (550, 600 and 650 rpm) were employed to obtain the optimal conditions for FSW of AZ31 magnesium alloy to 6061 aluminum alloy. The joint fabricated at 35 mm/min and 650 rpm, exhibited improvement of 28% in tensile strength and enhancement about three times in elongation, compared with the joint without nanoparticles. SiC nanoparticles had an effective role on the grain refining of the stirred zone and improving the microstructural characteristics of the banded structure zone. Due to the decreased grain size and the presence of ceramic nanoparticles (SiC) with high value of hardness, the hardness level of the reinforced samples was greater than that of the non-reinforced samples. Fracture of the non-reinforced sample was completely brittle, while in the reinforced samples, fracture features changed to the ductile mode.

“…Steels are progressively substituted by lightweight engineering alloys in these applications [3,4]. Among various lightweight engineering alloys, aluminum alloys have attracted considerable attention, due to their exceptional machinability, acceptable strength, and excellent anti-corrosion properties [5,6]. However, aluminum alloy welding suffers from problems such as solidification cracking and hydrogen-induced porosity, which restrict the potential applications of aluminum alloys [7].…”

Aluminum alloy welding suffers from problems such as solidification cracking and hydrogen-induced porosity, which are sufficiently severe to limit its potential applications. Because mitigated porosity incidence and solidification cracking are observed in aluminum welds using double pulsed gas metal arc welding (DP-GMAW), a comprehensive review of the mechanism is necessary, but absent from the literature. The oscillation of arc force and droplet pressure causes a weld pool stir effect. The expansion and shrinkage of the weld pool cause unusual remelting and resolidification of the previously solidified metal. DP-GMAW has an increased solidification growth rate and cooling rate, compared with conventional pulsed welding at same heat input. Both numerical and experimental results reveal the remarkable concept that refined microstructure in the fusion zone is obtained by using DP-GMAW. The mechanism of microstructural refinement is revealed as a weld pool stir effect and increased cooling rate. Hydrogen bubbles easily float out and then release from the weld pool originated from the weld pool stir effect. Reduced solidification cracking is achieved due to the refined solidification structure that originated from the increased cooling rate. The advantages, evolution process, and future trend of DP-GMAW are discussed.
