An experimental study on friction stir welding of Al-Si-TiB2 metal matrix composite

Multicriteria Selection of Friction Stir Welded Al-Tib2 Metal Matrix Composites using WASPAS to Improve Composite Development and Design

“…It explains the effectiveness of the responses created by the frictional heating of the workpiece as the revolving-translating tool strokes alongside the workpiece. This is distinctive from the intuition judgment of the machine workshop manager (Christy, 2010;Li et al, 2018;Karloopia et al, 2018;Balaji et al, 2018;Barati et al, 2019;Karpasand et al, 2020). Selection predicts the composite that will endure a long lifespan, adding accuracy to the manager's understanding of the shear and normal forces' dynamic blend.…”

“…Before the emergence of friction stir welding (FSW) in 1991, welding practices had been limited to the conventional welding (fusion) technique, which is extremely problematic (Karloopia et al, 2018). However, the breakthrough technology of FSW, patented by TWI, provided a profitable route to evade the problematic nature of conventional welding technique (Karloopia et al, 2018;Bocchi et al, 2018, Li et al, 2018Sharma et al, 2019). As the FSW became the centre of attraction in the scientific community, success was achieved as FSW showed the capability to join aluminium alloys.…”

“…By counting the gains of FSW, the research community appreciates the tremendous leap in productivity due to the adoption of FSW against the conventional technique of fusion welding. For instance, when knowledge was limited to fusion welding, the welding community was confronted with problems associated with reinforcement segregation, irregular spread, undesired reactions and defects (oxide creation at elevated temperature, and porosity) (Karloopia et al, 2018). However, the FSW breakthrough has brought enviable properties in welding and welding products, including energy efficiency, avoidance of solidification defects and grain refinements (Sharma et al, 2019).…”

“…The classic studies concerning Al-TiB2 (Sharma et al, 2019), Al-10%wt TiB2 (Vijay and Murugan, 2010), and on (TiB2)p6061-T6 have some interesting results on FSW. At the beginning of research on composite development in FSW, single reinforcements were the dominant substances but later researchers explored the synergic powers of two reinforcements in FSW activities, such as AA7005/TiB2-B4C (Pol et al, 2019) and Al-Si-TiB2 (Karloopia et al, 2018). A further study reveals the use of AZ31B magnesium alloys to reinforce AA6061 aluminium matrix (Jayarai et al, 2017).…”

“…Furthermore, the focus is on Al-TiB2 metal matrix composites because they are extensively used in numerous industries, including structural, automobile, aerospace, and naval vessels (Suresh et al, 2012;Vajagah et al, 2014;Chen et al, 2017;Pahdpilli et al, 2018). Although Al-TiB2 composites have been studied in diverse perspectives such as wear (Poria et al, 2018), vibration (Wang et al, 2019;Zhao et al, 2020), andmachining (Magibalan et al, 2019), as noticed in previous literature, there is a complete absence of knowledge on the objective perspective of ranking and choosing the best Al-TiB2 composites from the various Al.wt.% composites using the criteria of ultimate tensile strength, microhardness and ductility in the friction stir casting technique of production Karloopia et al, 2018;Mozammil et al, 2020;Sethi et al, 2020;Karpasand et al, 2020).…”
