In the current scenario, the development of high strength and low weight material is the demand of the aerospace defence organizations. Magnesium alloy based composite has low density, good mechanical and physical properties. In this study, magnesium alloy AZ31B is used as reinforcement material and graphene nanoparticle is used as reinforcement material. Stir casting technique is used for the development of composite material. Three weight percentages i.e. 0.4%, 0.8% and 1.2% are used for the casting. The microstructural analysis is performed to validate the presence of graphene particles in the developed composite. Further mechanical properties such as tensile strength, hardness and toughness are evaluated. Experimental results confirm that GNPs particles are uniformly distributed into the matrix material. It was observed that due to the reinforcement of GNPs particles tensile strength of the material is improved by 31.17%, hardness is improved about 46.9%. However, the peak value of toughness is observed 12.6 Jule/cm2 in the matrix material, it decreases by increasing the wt% of reinforcement particle and lowest value of toughness of 6.82 Jule/cm2 is observed in AZ31B/1.2%GNP composite.

“…At lower values of TOFF and bed speed and higher values of I and TON, improved surface finish and dimensional accuracy were attained. Nag et al, [23] analyzed the impact of process parameters on the machining performance of A359/Al2O3/B4C hybrid AMC produced by electromagnetic stir casting process. Analysis of the material removal rate and SR values showed TON as the most significant input variable.…”

Increasing demand for aluminum matrix composites (AMCs) in the manufacturing sector leads to the development of squeeze casted hybrid AMCs bearing superior mechanical attributes. Excessive hardness due to squeeze pressure and the presence of reinforcement particles makes the machining of AMCs challenging and results in excessive tool wear and inadequate surface finish. Wire electric discharge machining (WEDM) process has been preferred over conventional manufacturing processes for the machining of squeeze casted Al2024/Al2O3/W hybrid composite. This study investigates the selection of the most pertinent wire electrode for the precise machining of Al2024/Al2O3/W. Simple zinc-coated (NT) and cryogenic treated (CT) brass wire electrodes have been selected for machining. Scanning electron microscope (SEM) analysis of CT wire shows that cryogenic treatment enhances the soundness and stability by reducing microcavities in its microstructure. To analyze the effects of cryogenic treatment, the machining performance of CT wire has been compared with NT wire. Besides wire type, the influence of key input variables has also been analyzed on the imperative response measures including cutting speed (CS), surface roughness (SR) and kerf width (KW) to make the machining process more effective. Microstructural analysis of NT wire depicts a high concentration of micro-voids, micro-cracks, and deep craters, while the surface of CT has been observed relatively fine after the machining. Comparative analysis of both wire electrodes has declared that CT wire yields 26.96% and 15.10% superior results for CS and SR respectively, and 6.92% deprived results for KW than NT wire.

“…In Today's world, metal matrix composites (MMCs) are one of a suitable choice of material for most of the engineering application [1][2][3][4] . The tremendous properties like lightweight, anti-corrosion and improved mechanical and thermal properties increase its demand in the manufacturing industries [5][6][7][8] . However, the behaviour under machinability is also an important way of characterization of MMCs.…”

The performance evaluations of any manufacturing materials are significantly affected by their quality of surface as well as mechanical and metallurgical properties. MMCs are preferable material for the automobile and aircraft industries due to its excellent properties such as lightweight, high strength to weight ratio and high wear resistance. However, the presence of hard reinforcement particles in the matrix alloy makes it difficult to machine, which leads to the microstructural variation and extent of the subsurface damage. In the present study, three different rotational speed (varies from 200 rpm to 600 rpm) is used to turn the surface of previously in-house made hybrid MMC A359/2%B4C/2%Al2O3 on CNC lathe SPRINT 16TC made by BATLIBOI. An attempt is made to examine the 3D surface visualization and generate the surface roughness report by Micro-Prof FRT optical profilometer, surface topographical by Olympus Lext OLS 3100 laser confocal microscope for surface characterization. The results reveal the smooth machined surface with surface roughness ranges between 1.5 µm to 2.9 µm. The topographical images revealed a flat surface full of repetitive cutting marks parallel to each other and along the direction of cutting. There are no significant topographical differences are varying rotational speed.
