“…Also, cutting force and surface roughness were increased due to nano B 4 C reinforcement, which cannot improve machinability. Aluminum MMCs reinforced with SiC and B 4 C are more rigid and more wear-resistant when compared with Al 2 O 3 reinforcement [13]. In the context of MMCs reinforced with SiC or B 4 C having poor surface roughness, as reported by Kathirvel and Palanikumar [11] and Siddesh Kumar et al [5], Al 2 O 3 can be a better reinforcement to improve machinability characteristics.…”

“…In order to achieve the superior properties of MMCs for machinability studies, the stir casting technique is preferred to make LM24-nano Al 2 O 3 -Gr hybrid composites due to their low manufacturing cost with highquality composites [13]. The chemical composition of LM24 aluminium alloy [24] is shown in table 1.…”

This study investigated the machinability characteristics of the turning operation to attain the optimal combination of minimum surface roughness and the highest material removal rate. The analysis employed Response Surface Methodology (RSM). The study conducted a series of experimental runs using the Box-Behnken Design of Response Surface Methodology. The parameters of spindle speed, feed, and depth of cut were varied, while different weight percentages of reinforcements, including Al2O3 nanoparticles (at 1%, 3%, and 5% weight percentages) and Gr (at 1% weight percentage), were incorporated into the LM24 metal matrix alloy. Response Surface Methodology (RSM) analysis is carried out to optimize the turning machining parameters and enhance the machining performance for better quality and productivity. The derived optimal machining parameters have been verified through confirmatory tests. An analysis of variance (ANOVA) was used to determine the individual contributions of each parameter to the machinability characteristics. Surface morphology analysis revealed the smooth distribution of nanoparticle reinforcements to the metal matrix. The hardness and surface roughness of the machined nanocomposites were studied. Finally, the optimized output machining parameter of minimum surface roughness Ra and maximum material removal rate MRR are 0.522 μm and 110.2 mm3/sec were to be found, and the maximum hardness of the MMC composites was 60.5 HRB.

“…A graphite electrode with a theoretical value of 372 mAh g −1 was determined, which is lower to fulfill the current demands. Many approaches have been introduced to carbon-based materials to address these problems, including cellulose/Al 2 O 3 [ 34 ], Al into novel Li 3 VO 4 @C [ 35 ], Si/Ni 3.4 Sn 4 /Al/C composites [ 36 ], Al/metal oxide composites [ 37 ], and Al doped carbon Li 4 Ti 5 O 12 as lithium-ion batteries for anodes [ 38 ]. In addition, the expansion of silicon and the damage to the anode caused by electrolytes are relatively reduced.…”

With the ever-increasing world population, the energy produced from green, environmentally friendly approaches is in high demand. In this work, we proposed a green and cost-effective strategy for synthesizing a porous carbon electrode decorated with alumina oxide (Al2O3) from cherry blossom leaves using the pyrolysis method followed by a sol-gel method. An Al2O3-coating nano-layer (4–6 nm) is formed on the porous carbon during the composition fabrication, which further adversely affects battery performance. The development of a simple rich-shell-structured C@Al2O3 nanocomposite anode is expected to achieve stable electrochemical performances as lithium storage. A significant contributing factor to enhanced performance is the structure of the rich-shell material, which greatly enhances conductivity and stabilizes the solid–electrolyte interface (SEI) film. In the battery test assembled with composite C@Al2O3 electrode, the specific capacity is 516.1 mAh g−1 at a current density of 0.1 A g−1 after 200 cycles. The average discharge capacity of carbon is 290 mAh g−1 at a current density of 1.0 A g−1. The present study proposes bioinspired porous carbon electrode materials for improving the performance of next-generation lithium-ion batteries.

“…such as aerospace, automotive, and defense sectors. It may be recalled that different types of reinforcement materials are used, including silicon carbide, alumina, boron carbide, titanium carbide, Beryl and tungsten carbide [4][5][6][7][8]. Among the reinforcement materials tried to produce MMC's, hardly a few literatures could be cited regarding the deployment of Beryl particles in Al 2024 matrix and the connected information on the properties.…”

The adoption of Aluminum Metal Matrix composites has gained popularity and widespread application in view of their light weight and superior mechanical strength compared to the un-reinforced alloy system. Much improved characteristics have been derived based on the adoption of secondary processes such as rolling, forming, drawing and plastic deformation. In this context, the preparation of Al2024 alloy, containing Beryl particles as reinforcement is envisaged for getting better properties in terms of strength and hardness for structural use in aerospace industry. Further enhancement in properties to strengthen the alloy may be possible by subjecting it to severe plastic deformation, especially Equal Channel Angular Pressing (ECAP) process. The present work focuses on developing Al 2024 alloy composites containing Beryl particles at 6 wt.%, through stir cast method. This is followed by ECAP process carried out in the annealed condition. This facility has been designed and developed in house. Following this, the mechanical properties, involving tensile strength, % elongation & hardness have been evaluated for the ECAP processed Al2024 Beryl samples and the values thus obtained are compared with those derived on samples without Beryl additions. The microstructures of the samples, for key stages of the work, have been recorded. Further, the fracture morphology of ECAP processed samples have been examined and analyzed using SEM/EDAX and correlated with the tensile strength data. The ECAP with pass II processed samples have shown higher tensile strength and hardness as well as good grain refinement in the matrix compared to annealed Al alloy sample.
