A Study on Mechanical and Tribological Properties of Al Alloy 7068 MMC’s Reinforced with SiC and Tur-Husk

Abstract

There is a growing need for composites made of aluminum metal. The hybrid nature of the composite is due to the addition of the third element to the metal matrix. Aluminum 7068 was employed as the matrix, while Silicon Carbide and Alumina were used for reinforcing. To examine how the proportion of reinforcement affects the aluminum's properties, we experiment with different values. The first sample is Al7068 with 2% SiC and 8% Al2O3, the second sample is Al7068 with 4% SiC and 6% Al2O3, the third sample is Al7068 with 6% SiC and 4% Al2O3, and the fourth sample is Al7068 with 8% SiC and 2% Al2O3. Stir casting is used to get the necessary components. The composite specimens were machined to ASTM specifications after being cast. The purpose of this research is to examine the mechanical and tribological characteristics of Al-7068 alloy that has been reinforced with SiC and Al2O3 composite with varying weight fractions.
