Abstract

The utilization of Aluminium composites in the defense and aerospace industries has skyrocketed recently. Due to their low density combined with high strength and stiffness, aluminum-lithium (Al–Li) based composites have increased in popularity in recent years. Lithium (Li) can be used to reduce density while also increasing strength and stiffness. Despite this, aluminum–lithium (Al–Li) composites have gotten comparatively little research. Silicon Carbide (SiC) particles were found to be an outstanding reinforcement with the Aluminium-Lithium (Al-Li) matrix among the numerous ceramic reinforcements tested. The addition of Silicon Carbide (SiC) particles to the Aluminum matrix increases the material’s strength and young’s modulus, hence increasing its particular qualities.In comparison to the unreinforced alloy, the Aluminium-LithiumSilicon Carbide (Al-Li-SiC) composite has superior mechanical properties. Stir Casting Technique can be used to determine Mechanical Properties such as Tensile Strength, Compressive Strength, Hardness, and Wear Resistance of Aluminium- Lithium-Silicon Carbide (Al-Li-SiC) composite.
