EffEct of Stir caSting ProcESS ParamEtErS and StirrEr BladE gEomEtry on mEchanical ProPErtiES of al mmcS -a rEviEwaluminium matrix composites offer a combination of properties such as lower weight, higher strength, higher wear resistance and many more. The stir casting process is easy to use, involves low cost and is suitable for mass production compared to other manufacturing processes. an in-depth look at recently manufactured aluminium matrix composites and their impact on particle distribution, porosity, wettability, microstructure and mechanical properties of al matrix composites have all been studied in relation to stirring parameters. several significant concerns have been raised about the sample's poor wettability, porosity and particle distribution. Mechanical, thermal, and tribological properties are frequently studied in conjunction with variations in reinforcement proportion but few studies on the effect of stirrer blade design and parameters such as stirrer shape, dimensions and position have been reported. To study the effect of stirrer blade design on particle distribution, computational fluid dynamics is used by researchers. reported multiphysics models were k-ε model and the k-ω model for simulation. it is necessary to analyse these models to determine which one best solves the real-time problem. stirrer design selection and analysis of its effect on particle distribution using simulation, while taking underlying physics into account, can be well-thought-out as a future area of research in the widely adopted stir casting field.

“…G. Karthikeyan et al [16] fabricated an aluminium matrix composite with LM6 aluminium alloy as a base matrix and ZrO 2 as reinforcement in varying weight percentages varying from 0-12% using the stir casting technique. The sample specimens then underwent microstructure analysis as well as mechanical and thermal analysis, and the results concluded that the composite with 12% by weight ZrO 2 had the maximum tensile and compressive strength of 209 MPa and 218 MPa, respectively, along with better heat transfer rate, efficiency, and effectiveness, which made it the ideal fin material, among others.…”

The wear debris from conventional brake pads is a growing source of environmental contamination that often leads to life-threatening diseases for human beings. Though the emerging organic brake pads show potential to serve as an eco-friendly alternative, their mechanical and tribological properties are not adequate to withstand the demands of high-wear resistance of a functioning braking system under regular use. Metal matrix composites have served as an optimal solution with minimal environmental pollution and appreciable physical properties. Owing to the popularity of aluminium metal matrix composites, the present study is based on the fabrication and characterization of SiC-reinforced LM6 alloy through stir casting methodologies for evaluating its worthiness in application as a brake pad material. Microstructural, compositional, and phase characterizations were executed through optical micrography, X-ray diffraction, and energy-dispersive X-ray spectroscopy analysis. Although mechanical properties were evaluated through surface hardness investigation, parallel thermal properties were estimated through thermal conductivity evaluation. Finally, the execution of tribological analysis and precise microstructural observations of wear track at ambient and elevated temperatures helped in establishing the datum that the fabricated metal matrix composite (MMC) is a reliable brake pad material alternative.

“…For MMSF characteristics of the hollow reinforcements such as porosity percentage and wall thickness also affect the mechanical properites 45 . Among the most reported reinforcements for AMC are carbides (SiC, B 4 C, WC, TiC) [46][47][48][49][50][51][52] , oxides (Al 2 O 3 , SiO 2 , TiO 2 , ZrO 2 , Y 2 O 3 , MgO, CeO 2 ) [53][54][55][56][57][58] , nitrides (Si 3 N 4 , BN) [59][60][61] and Carbon Nanotubes (CNTs) [62][63][64][65][66][67] . For the case of syntactic foams there have been mainly reported metallic or ceramics hollow spheres, being Fe, SiC, SiO 2 and Al 2 O 3 the most used [40][41][42][43][44][45][68][69][70][71][72] .…”
