“…Moreover, grain refinement is likely to occur owing to dynamic recrystallisation [18, 19]. Similar FSW of various Al-matrix nanocomposites has been attempted [5, 20-24]. FSW has been successfully used to join aluminium alloys, especially the precipitation-hardened (2xxx, 6xxx, and 7xxx) ones [8, 9].…”

Owing to the advantages of nanocomposites for structural applications, we present microstructural evolutions and texture development during dissimilar friction stir welding (DFSW) of an Al-matrix hybrid nanocomposite (Al-2 vol.-% Al 2 O 3 -2 vol.-% SiC) with AA1050. It is shown that DFSW can successfully be performed at a rotating speed of 1200 rev min −1 and a transverse speed of 50 mm min −1 while locating the nanocomposite at retreating side. Formation of macro-, micro-, and nano-mechanical interlocks between dissimilar base materials (BMs) as a result of FSW tool stirring action possessed an impact influence on the mechanical performance of dissimilar welds. Electron microscopy revealed formation of a three-modal grain structure from microscale ( > 1 µm) to nanoscale ( < 100 nm) range in the stir zone of the joint materials. Texture components included a mixture of {112} < 110 > shear elements and ideal B/B random orientations, as compared to the completely random and Cu-P preferred textures for the aluminum and composite BMs.

“…Lastly, the heat-affected zone (HAZ) is only exposed to thermal cycles during the welding process. Therefore, its grain size is approximate to the base metal's grain size and has the lowest mechanical properties due to its elongated grains [6].…”

“…Friction-stir welded aluminium matrix composite (AMC) joints find application in the areas of automobile, naval and aeronautical engineering, due to their attractive characteristics like higher strength, lower density, excellent corrosion resistance, better thermal conductivity, low thermal expansion, and better dimensional stability with good strength to mass ratio [1][2][3][4][5][6]. AMC, being an ideal material for this new generation, also faces many problems in welding by conventional fusion welding owing to the reaction between matrices and particulates of reinforcement that lead to the development of secondary brittle phases in the molten pool of the weld or reinforcement breakdown in the molten pool of metal [7].…”

In the present investigation, aluminium-based alloy (AA6082) is stir-casted with 3 % ZrO2 and 5 % B4C reinforcement particulates to fabricate Aluminium Metal Matrix Hybrid Composites (AMMHCs) which are further friction-stir welded at different welding conditions to develop a welded joint with optimum ultimate tensile strength (UTS) and microhardness. This newly developed AMMHC will find its specific application as bulkhead partitions in the hull of a ship due to its excellent properties, such as lower weight, higher specific strength, superior resistance to wear, and lower thermal expansion coefficient than that of AA6061 and AA5083 composites. The friction-welded butt joints performance of AA6082/3%ZrO2/5%B4C is generally determined by varying the FSW process parameters such as tool rotational speed (TRS), welding speed (WS), axial load (AL), tool tilt angle (TTA), tool pin profile (TPP), shoulder diameter (SD), etc. In the present work, the empirical relationships are established between parameters highly influencing FSW process (TRS, WS, and AL) and their responses (UTS and weld nugget microhardness (WNH)). The desirability approach is employed for predicting the optimal UTS and WNH. The corresponding values of input process parameters are TRS of 1030.95 rpm, WS of 38.5 mm/min, and AL of 5.88 kN. The calculated UTS and WNH for the present investigation are 239.98 MPa and 94.2 HV, respectively, and these values are consistent with the results of validation experiments.
