“…Furthermore, FSP causes grain refnement in the majority of alloys. Kumar et al [24] studied the mechanical characteristic effciency of nanosized reinforcements by promoting more implicit particle hardening mechanisms compared to micron-sized reinforcements. In this study, the SEM image of SiC is employed.…”

In this study, friction stir processing (FSP) was used to create new surface properties of the Al 6101-SiC composite, and different types of friction stir process tools are used like cylindrical with thread and conical with thread. The SEM and EDAX analyses made it evident that texture appeared in FSPed Al6101 both with and without SiC. Due to the refined grain structure and the inclusion of SiC in the composite, both FSPed samples’ hardness and tensile strength were found to be higher than those of the base alloy. In contrast to FSPed and base material, the composite had a lower percentage of elongation. Drilling experiments led to machining research that showed FSPed Al6101 to have larger cutting forces than the base and composite materials. These findings revealed that SiC served as reinforcement in the material, increasing hardness and cutting forces during drilling. Electrochemical tests on the corrosion behavior showed that the composite had less corrosion resistance than the FSPed alloy but had slightly better corrosion resistance than the base material. Al6101-SiC composites were found to have superior mechanical characteristics and greater machinability. However, when creating an Al6101-SiC composite via FSP, it is crucial to consider corrosion resistance degradation.

“…Using the blind drilling method has several advantages compared to longitudinal grooves, such as better control over the powder distribution and, therefore, the ability to control the surface properties based on the specific application. Kumar et al [19] also utilized blind holes to modify the surface of AZ31 by incorporating Al 2 O 3 . Three specimens were employed to examine the impact of tool rotational speed on welding properties in addition to non-reinforced processed specimens.…”

The utilization of Al2O3 nanopowder to reinforce AA5754 aluminum alloy through blind holes employing the friction stir processing (FSP) technique to produce an aluminum matrix nanocomposite is explored in this paper. Motivated by the necessity to enhance the strength and ductility of welded joints, the impacts of varying the tool rotational speed (rpm) and blind hole diameter on the microstructure and mechanical properties of the joints are investigated. Experimental characterization techniques including SEM, optical microscopy, microhardness, and tensile tests were employed to analyze the welded joints produced under different processing parameters (tool rotational speeds of 910, 1280, and 1700 rpm, and blind hole diameters of 0, 1, 1.5, and 2 mm). Comparative analyses were conducted against base metal properties and joints without reinforcement powder. It was found that the addition of nanopowder resulted in a decrease in the maximum generated heat during FSP, while also reducing the stir zone size compared to samples without nanopowder. Moreover, enhancements in both the strength and ductility of the joints were observed with the incorporation of Al2O3 nanoparticles. The optimal combination of welding conditions, observed at 1280 rpm rotational speed and 1.5 mm hole diameter, yielded a remarkable ultimate tensile strength of 567 MPa, accompanied by a hardness of 45 HV. These results underscore the potential of nano-Al2O3 reinforcement in significantly improving the mechanical properties of the produced nanocomposite, with implications for advancing the performance of welded structures in various engineering applications.

“…Natural energy sources are being depleted as a result of rising worldwide prices and increased energy consumption [3][4][5]. The combustion of fossil fuels has a number of negative effects on the environment, including a rise in the emissions of greenhouse gases (GHG), mainly CO2 [6,7]. Global primary energy consumption has sharply expanded in recent decades as a result of rapid industrialization and rising living standards [3,8].…”

Recently, biodiesel has become more attractive owing to its attractive properties such as positive environmental effects, non-toxic, biodegradable, derived from renewable resources. Hence, this paper aims to provide an overview on biodiesel production and generations of biodiesel produced from distinct feedstocks. Thereafter the comparison of fuel properties, oil yield for different edible and non-edible oil and feedstock cost in distinct countries is given. Finally, the properties of biodiesel developed from distinct feedstock are summarized. The outcome demonstrates that the various sources offered varying yields owing to the process factors. However, the yield of biodiesel varies w.r.t. feedstocks owing to the physical and chemical characteristics of the sources and the process factors. Among waste cooking oil, commercial diesel fuel, and biodiesel from waste cooking oil, waste cooking oil offered higher pour point (284K), density (0.924 kg/L), water content (0.42%), kinematic viscosity (36.4 mm2/s) than commercial diesel fuel and biodiesel from waste cooking oil.
