“…The AS4 HAMC sample had the lowest % void content, with 4.5 wt% Gr and 4.5 wt% SCBA. Gr is a solid lubricant that enables filler particles in the Al matrix to move and reorganize [67]. As a result, raising Gr contents in HAMCs to a certain limit is considered beneficial for obtaining minimal porosity [68].…”

Hybrid aluminum matrix composites (HAMCs) are a new class of advanced materials that can be customized and engineered to achieve specific properties for specific applications in specific environments. HAMCs find a wide range of popularity in the transportation sector because of lower noise and lower fuel consumption over other materials. This research aims to synthesize, characterize, and test the physicomechanical characteristics of tetra hybrid (SiC, Al2O3, Gr, and sugarcane bagasse ash (SCBA)) reinforced HAMCs via powder metallurgy (PM) processing. Tetra hybrid reinforced HAMCs were synthesized using a pure Al matrix with fixed wt% of primary reinforcements (5 wt% SiC and 5 wt% Al2O3) and varying wt% of secondary reinforcements such as 0.5, 2.5, 4.5, and 6.5 wt% Gr and 0.5, 2.5, 4.5, and 6.5 wt% SCBA. It mainly focused on phase purity investigation using XRD, thermal analysis using TGA-DTA, and surface area and micropore size analysis using BET and physicomechanical tests to explore the materials’ behavior of the newly synthesized HAMCs. The increase in wt% of secondary reinforcements decreases both the density and porosity while increasing the hardness and compressive strength up to a certain level above which it begins to reverse because of the increase in wt% of hard particles of SiC, Al2O3, and SCBA. The Vickers hardness and compressive strength of the AS4 HAMC with 10 wt% (SiC+Al2O3) and 9 wt% (Gr+SCBA) were improved by 446.40% and 209.75%, respectively. The newly synthesized tetra hybrid reinforced HAMCs showed superior physicomechanical properties compared to pure Al and single and double reinforced HAMCs. As a result, the new tetra hybrid reinforced HAMC material is predicted to have potential applications in automotive, aerospace, defense, and various other structural applications.

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.

“…When genome sequencing was done by Indian SARS-CoV-2 Consortium on Genomics (INSACOG) it was found two important mutations in single variant and is termed as “double mutant” [7] . The rapid growth of this variant caused large destruction in India and still the panic situation continues and this clearly indicates the role of this variant in India’s surge and the destruction is even far more as compared to first wave of corona infection in the year 2020 [8] . Other reason of India’s surge could be the people lowered the guards and did not follow the COVID-19 protocol after the first wave.…”
