“… The current investigation found that the machinability of each sample varies with wt%, the hardness of machined AMMCs is significantly affected by wt% of supplements, both individually and collectively. Since the strength of AMMCs must be improved [45], the high wt% of brittle SiC and ZrSiO4 was added to the matrix alloy; optimal machining conditions are required. The machined profile becomes harder as the SiC weight percentage rises.…”

Aluminum metal matrix composites (AMMCs) have become increasingly ubiquitous in the fields of aerospace and automobile businesses due to their lightweight properties. Their machining is a challenging task because of the presence of supplemented particles, also called reinforcements. As the wt% of the supplemented particles changes, the morphological and machining behaviors of the AMMCs change. The present work is focused on exploring the thermo-mechanical properties of AMMCs which would help in AMMC applications in the aerospace industry with a new collection of composites containing silicon carbide (SiC) and zircon/zirconium silicate (ZrSiO4) as supplements in wt% of 5%, 20%, 30%, and 40%. Uniform binary and hybrid sample pallets are prepared by powder metallurgy (PM). The said samples are sintered and then machined using wire electric discharge machining (WEDM) employing brass wire with a feed rate of 2 to 3 mm/min. Also, analysis of porosity and recast layer formation is performed via the microstructure, scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS). Some interesting and useful findings are obtained which can extend the applications of AMMCs in automobiles and the aerospace industry. The results reveal that temperature and wt% are playing their significant roles in the changes in the thermo-mechanical properties of AMMCs. Mathematical equations via regression analysis using Minitab 17 and Excel are developed for the congruence of experimental data. Analysis of Variance (ANOVA) is also performed. Hence, the most optimized relationships for the best machining output are established and presented in this proposed study.

“…Density, tensile strength, yield strength, weldability, ductility, formability, workability and corrosion resistance are the common factors that should be considered while choosing an alloy for a certain application. Other than Al in the alloy, Si, Mn, and Mg are the other common elements of the Al6063 alloy, which is extensively employed in structural applications [20]. Al6063 is commonly used in ship construction as a result of its increased strength and greater capacity to withstand sea environment.…”

The aim of the current work is to explore the machinability behavior of Al6063/WC/ZrO2 metal matrix composites (MMC) produced through a stir casting process through wire electrical discharge machining (WEDM) process. In order to examine the effects of process parameters such as voltage (V), pulse on time (Ton) and pulse off time (Toff) on material removal rate (MRR) and surface roughness (SR). The experiments were conducted by adapting Response Surface Methodology (RSM) in conjunction with the central composite design (CCD). A second-order regression model has been developed to predict the response parameters and an analysis of variance (ANOVA) was performed to validate the significance of the models. Using the desirability function approach, the parameters were set for the highest MRR and the minimum SR value. The prediction was within a tolerable average error range. A total of 19 sets of tests were developed to obtain six possible solutions. The most suitable solution among these six has been found by a confirmatory experiment. The results indicate that voltage and its interactions have significantly affected both the responses than Ton and Toff. Overall, it can be said that the study of the Al6063/WC/ZrO2 MMCs using WEDM process parameters demonstrated improved casting and machining qualities.

In manufacturing, material machining plays a vital role in fabricating a wide variety of components and structures. Metal matrix composites (MMCs) exhibit unique behavior during the machining process compared to conventional metals and alloys because of their multiphase composition with distinct physical and mechanical properties. This research investigates the machining behavior of Al6063-TiO2 composites on the non-conventional machine, which is known as E-D-M machine, and assesses the influence of E-D-M machine process performance factors on this behavior. Using the stir casting technique, Al6063-TiO2 composites with different TiO2 concentrations, ranging from 1% to 5% by weight, were synthesized. The resulting composites were characterized, revealing that the composite with 5% TiO2 concentration showed the highest hardness. The study aimed to identify the optimal EDM machining parameters for these composites by conducting a series of experiments. The EDM machining based experiments involved four factors at four levels: current (4-10 A), POT (pulse on time) (ton, 60-120 μs), POFFT (pulse off time) (toff, 20-26 μs), and pressure (0.6-1.2 atm). This study investigates the impact of introducing TiO2 nanoparticles ranging in size from 55 nm to 100 nm into Al6063, with the majority falling within the range of 55 nm to 70 nm. The findings show that, when the percentage of TiO2 nanoparticles grew up to 5 percent, the composite's strength increased proportionally. The largest improvement seen was almost 20% stronger than the base metal Al6063. Besides the increase in strength, a rise in the composite's corrosion resistance was also seen, with the composite exhibiting the best resistance at a 5 percent TiO2 concentration. A similar tendency was also observed in the composites' wear resistance. However, the volumetric wear rate increased significantly when subjected to a 3 kg weight. This study emphasizes the significance of TiO2 nanoparticle concentration in regulating the mechanical and electrochemical properties of Al6063-TiO2 composites. These findings provide valuable data that could guide future efforts to enhance these parameters for a variety of industrial applications. Delta values ordered current, pulse-on time, pressure, and pulse-off time in order of relevance. This ranking helps optimize Al6063-TiO2 composite EDM process parameters for better machining. This extensive investigation shows that TiO2 nanoparticles significantly affect the machining behavior of Al6063-TiO2 composites when EDM is applied. The findings clarify the relationship between EDM performance characteristics and Al6063-TiO2 composite machining behavior, providing vital data for industrial applications. The findings also open the door to studying the machining features of comparable metal matrix composites and improving their mechanical and electrochemical properties.
