“…Aluminum alloys have a wide range of use, especially in the automotive and aerospace, electronics, machinery, and manufacturing industries due to their high strength compared to their weight, high mechanical properties such as low density, high corrosion resistance, and easy machinability. [1][2][3][4] However, the mechanical properties of many aluminum alloys such as tensile strength, hardness and wear resistance are lower than these mechanical properties of other materials commonly used in the industry. 5 Therefore, superior mechanical properties can be obtained by adding reinforcement material to the aluminum matrix.…”

“…14 In the literature, there are also studies examining the mechanical properties of WC reinforced aluminumbased composite materials, such as tensile strength, [15][16][17][18] impact resistance, 17 hardness, [15][16][17][19][20][21] density, 15,[19][20][21] and wear resistance. 16,[20][21][22] Ravikumar et al 23 examined the mechanical properties of composite materials such as hardness and tensile strength by adding WC in different proportions (2,4,6,8, and 10 wt.%) by weight to AA6082 aluminum matrix by stir casting method. As the WC reinforcement ratio increased, the hardness also increased.…”

Aluminum-based metal matrix composites are extensively used in applications in many industrial fields, especially in the aviation and automotive industry. The usage rate is increasing day by day. Therefore, it is very important to improve the mechanical properties of the composite structure. For this purpose, in this study, 3, 5, and 7 wt.% tungsten carbide (WC) reinforced aluminum matrix composite material was produced by stir casting method. The mechanical properties (tensile strength, hardness, wear) of the produced composite materials and their effect on machinability were investigated. The machinability process was performed in constant cutting speed, constant cutting depth, three different feed rates (0.05, 0.1, and 0.2 mm·rev−1), and dry environmental conditions. Wear tests were performed on dry sliding conditions, under 25 N load, covering different distances (150, 300, 450, and 600 m). In addition, the microstructure of the composite samples was analyzed using optical microscopy and scanning electron microscope. The phases in the composite material were determined using the X-ray diffraction technique. As a result of the experiments, with the addition of WC particles, the mechanical properties of the materials such as tensile strength, hardness, and wear resistance have increased and the machinability capability has decreased.

Aluminum is a material with advantageous properties such as lightness, good conductivity, high plastic deformation ability, and superior corrosion resistance. However, aluminum and many aluminum alloys have disadvantages in terms of mechanical properties such as hardness, tensile strength, and wear resistance. To overcome this disadvantage of aluminum, it is a good method to add ceramic particles to the matrix. For this purpose, in this study, B4C (boron carbide)-reinforced AA2014 aluminum matrix composites were fabricated at 3%, 5%, and 7% reinforcement ratios using the stir casting method. Tensile tests, wear tests, cutting force measurements, and microhardness measurements were performed to determine the fabricated composite materials’ mechanical properties. Scanning electron microscopy and optical microscopy were used to analyze the microstructure of composite. X-ray diffraction analysis was utilized to study the phase identification. As a result of the study, it was observed that with the increase in the B4C reinforcement ratio, the mechanical properties of the aluminum matrix composite material, such as wear resistance, cutting strength, and hardness, increased. On the other hand, the change in tensile strength did not occur in this way. Tensile strength first increased and then decreased. The highest value of tensile strength was achieved at 5% B4C reinforcement. X-ray diffraction results showed that AA2014 and B4C were the fundamental elements in composites and are free from intermetallics.

“…MQL MF strategy reduced cutting temperature up to 16% in comparison to dry cutting, 6% in comparison to RHVT, and 10% as compared to compressed air. The temperature recorded was low under MQL MF strategy as MQL lessens heating between tool and workpiece by pulverizing the oil in the system with compressed air [47].…”

We primarily need to reduce the consumption of metalworking fluid to ensure sustainable and eco-friendly machining of aerospace alloys. The present study was planned to determine the efficiency of various eco-friendly metalworking fluid strategies for the sustainable turning of aerospace aluminium alloy (Al7075-T6) coated carbide tools under different eco-friendly metalworking fluid strategies namely dry machining, minimum quantity lubrication (MQL), Ranque-Hilsch vortex tube (RHVT), and compressed air. Machining performance was investigated in terms of micro-hardness, tool tip temperature, tool wear, cutting forces, work surface roughness, chip morphology, and energy consumed. Results manifested that MQL and tool coatings can significantly lower tool tip temperature by up to 16%, tool wear by up to 102-106%, average cutting forces by 17-21%, and surface roughness reduced from 11-21% as compared to dry conditions.
