An experimental investigation and comparison of mechanical properties of Al7075-SiC-Al2O3-Zro2 composites of automotive applications.

The purpose of this research to produce and describe composites consisting of Al, SiC, Al2O3, and ZrO2. In order to accomplish this goal, the matrix of aluminum (Al) was fortified with micron-sized powders of silicon carbide (SiC), zirconium dioxide (ZrO2), and aluminum oxide (Al2O3) in two different proportions: I Al90 %-5 %SiC – 2.5 % Al2O3 −2.5 % ZrO2 and (ii) Al 92.5 %-2.5 % SiC – 2.5 % Al2O3− 2.5 percent ZrO2. During the process of casting, the powder after being combined was poured. An examination of the material's microstructure confirmed the presence of reinforcements and their even distribution throughout the Al matrix. There was no evidence of severe agglomeration. It was noticed that the mechanical properties of cast composites, including tensile strength, compression resistance, and hardness were improved along with an increase in the concentration of silicon carbide particles inside the matrix. When contrasted with the cast composition, it was discovered that the optimal composition consists of 90% aluminum, 5 % silicon carbide, 2.5% aluminum oxide, and 2.5 % zirconium dioxide. Additionally, the composition may be appropriate for the production of Automotive applications. [ABSTRACT FROM AUTHOR]
