Aluminum is used in a wide range of industries, including the automotive, transportation, aerospace, minerals, and marine sectors, due to its high strength, stiffness, and wear resistance. It improves its qualities by including ceramic-fired bricks, fly ash, silicon carbide, tungsten carbide, and boron carbide as reinforcements. Stir casting is the most common and cost-effective method for processing and creating metal matrix composites, depending on the processing parameters, reinforcement, and matrix choices. All through the mix projecting interaction, a grid of aluminum 7475 is built up with changing extents of graphite (3, 6, 9, and 12 wt%) and coconut shell ash (10 wt%). This study found that stir-cast aluminum matrix cast composites have improved properties in terms of hardness and tensile strength. It also shows that when coconut shell ash powder and graphite are used as reinforcements, the AMMCs' coefficient of thermal expansion and thermal conductivity decrease. AMMCs' SEM images demonstrate the successful integration of reinforcements into the Al 7475 matrix. [ABSTRACT FROM AUTHOR] |
