“…Excellent mechanical properties, good corrosion resistance, and adequate ductility of high-strength Al alloys led to significant attention in various industrial sectors [14], including aviation and automotive industries to replace steel components with much lighter parts of aluminum-based materials [15]. The Al and its alloys are usually utilized in different parts of the vehicle engine like pistons, cylinder heads, and engine blocks [16], whereas pumps, injectors, starters, ignition coils, and heat exchangers are made of Cu and its alloys [17].…”

The anticorrosive effect of methanol extract of Tinospora cordifolia stem for Al and Cu metals in pure biodiesel and its 10% blend with petrodiesel was investigated at 25±2 °C in a closed system by corrosion, inhibition efficiency, adsorption, and electrochemical tests. The corrosion inhibiting action of the plant extract for Cu in the biodiesel was more efficient than in the blend, while the extract showed more anticorrosive behavior of Al metal in the blend than in the biodiesel. Adsorption of the plant extract on the metal surface conformed to the Langmuir adsorption model. The plant extract functioned as a mixed-type corrosion inhibitor for both the metals in both biodiesel and its blend based on the experimental results. Outcomes of the study confirm the suggestive evidence to formulate the green extract-based biodiesel additives to enhance the anti-corrosive response for the Al and Cu metal parts of the vehicle engine. Nepal-origin Tinospora cordifolia stem extract could be used as an anticorrosive agent to control the corrosion of Al and Cu metals in biodiesel-based fuels.

“…Aluminium alloy has the characteristics of low density, high specific strength and good corrosion resistance, which is widely used in transportation, aerospace, energy and power fields [1][2][3][4]. Aluminium-based lightweight materials offer great potential for novel engineering applications, particularly when they are optimised to exhibit high strength and yet provide sufficient reliability [5]. However, aluminium alloys also have low hardness, low elastic modulus and poor wear resistance, which limits the further application of aluminium alloys in engineering.…”

Graphene(GNPs) aluminum matrix composites have been widely used in transportation, aerospace, energy and power fields due to their high strength, good wear resistance and small thermal expansion coefficient. In this paper, AlSi10Mg-(0,0.5,1.0,2.0,4.0wt.%)graphene composite powders were prepared by vacuum mechanical milling, and then high quality composites were fabricated by selective laser melting(SLM). The SLM process of the composites was optimized, the microstructure and mechanical properties of AlSi10Mg-(0,0.5,1.0,2.0,4.0wt.%) graphene composites were analyzed. The results of scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy(EDS) and X-ray diffraction(XRD) showed, with the addition of graphene, the microstructure and mechanical properties of the samples are greatly affected. This benign change in the microscopic level has brought the improvement of mechanical properties to the sample.

“…In the past, aluminum alloy extrusions were mainly used as building materials. However, as the aluminum alloys with improved strengths to replace steel are being developed, their usage for automotive applications is gradually increasing [1][2][3][4][5]. Aluminum alloy parts are manufactured mainly through sheet and press forming, and bulk forming, such as forging and extrusion.…”

In this study, the plastic anisotropy distribution of an extruded 7075 aluminum alloy thick plate was evaluated through small-cube compression tests. The extruded plate with a thickness of 15 mm was divided into five layers in order to verify the difference in plastic anisotropy along the thickness direction of the extruded thick plate. Small-cube specimens with a side length of 1 mm were extracted from each layer and subjected to compression tests in each direction to evaluate the directional r-values of the extruded material. The r-values were applied to Hill’s quadratic yield criterion to calculate the six coefficients for each layer. To consider the plastic anisotropy in the thickness direction, a finite element model divided into five layers in the thickness direction was applied. Upsetting tests were conducted to verify the accuracy of the finite element analysis using cube specimens with a side length of 15 and 10.6 mm, and the results of the finite element analysis and the upsetting test were compared and analyzed against each other. Consequently, the finite element analyses were precisely simulated the upsetting test results.
