“…It's distinctly observed that the average grain size of AF5, AF5C1 and AF5C3 are much smaller than that of unreinforced Al6061. This result corresponds to previous studies [14,15] that the presence of reinforcement particles lead to the small grain nucleation during the solidification process. Sreekumar et al [16] and Harini et al [17] observed the reduction in grain size in Al-MgAl2O4 composites.…”

Phase formation, impact resistance, and fracture surface were investigated in unreinforced Al6061, Al6061-5wt% fly ash and Al6061 hybrid composites containing 5wt% fly ash and 1,3 wt% CaO. The Al6061 composites were fabricated the stir casting process. The XRD patterns reveal the formation of second phases (MgAl2O4, CaAl4O7 and MgSiO3), which were found in the Al6061 hybrid composites. The average grain size of Al6061 hybrid composite are much smaller than that of unreinforced Al6061.The impact resistance was enhanced by approximately 67% in Al6061 hybrid composite as compared to unreinforced Al6061 alloy. Brittle fracture indicting brittle fracture was observed in unreinforced Al6061 alloy while evidence of a mixture of brittle and ductile fracture was found in the Al6061 hybrid composites.

“…Also 95% confidence interval has shown increase in BHN with increasing in reinforcement. If only Bagasse ash reinforcement is used increase in properties is achieved but major loss of material takes place at the time of casting due to maximum slag formation (due to the presence of carbon and oxygen) [11], to reduce this desirable effect graphite is used for more enhancement in mechanical properties, which has resulted in reduced slag formation and less loss of material.…”

Waste sugarcane bagasse-ash and graphite utilizing as reinforcement in fabricating of an aluminium alloy (Al-7075) based matrix hybrid composites. The aluminium matrix hybrid composites have been fabricated by stir-casting method at 750 °C. Casting was developed in circular metal mould having 5 circular slots of diameter of 21 mm and length of 250 mm. Adding bagasse-ash with varying reinforcement of three cases, in first case 2% constant with varying graphite 1%, 3%, and 5%, in second case 4%, and in third case 6% constant with varying same graphite percentage. The effect of the reinforcement has been performed through various mechanical tests. The mechanical properties measuring such as Brinell hardness and tensile strength of both the samples have been prepared as per the ASTM E23 and E8 standards. Results give out that there will be greater effect of reinforcing different bagasse-ash in aluminium alloy matrix hybrid composites. In the third case more enhanced mechanical properties have been achieved as compared to case one and two of bagasse–ash combination. It shows that the selection of bagasse-ash as reinforcement has one of the most significant criteria for the fabrication of aluminium matrix hybrid composites.

“…It has been shown that increasing the amount of FA in the composite increases the EMSE, improving the composite's shielding properties by increasing its reflectivity. Tensile strength is reduced in composites with higher FA concentrations [23]. Due to its low density and ability to decrease weight and increase energy dissipation (EMSE), FA is considered a potential reinforcing ingredient for the composite.…”

Nowadays, fly-wire is only used for flying-related things. All plane controls depend on electronics, but they also must deal with high-intensity radiated fields. This equipment might need an electromagnetic shield to protect it from outside electromagnetic pollution. The current work aims to develop a mesh around the operating equipment to protect and make it work better. AL6061 was used to create a shield with a metal matrix composite. Here three combinations of Metal Matrix Composite (MMCs) were considered to protect from the high-intensity radiated fields. These MMCs are AL6061+10%Al_2 O_3+5% FA (MMC-1), AL6061+15% Al_2 O_3+5% FA (MMC-2), and AL6061+20% Al_2 O_3+5% FA (MMC-3) made the process of shielding more effective at different percentages. Explements are Measures that take the electrical characteristics, and they are by Shielding Effectiveness (SE) of different concentrations of fly ash and Al_2 O_3.SE of 50 dB is achieved; hence these MMCs can be used in aircraft and other applications as a shield.
