This study presents the mechanical characterization of an aluminum-lithium (Al-Li) alloy reinforced with alumina (Al2 O3) particulates to form a metal matrix composite (MMC). The objective is to evaluate the improvements in mechanical performance-tensile strength, hardness, impact resistance, and microstructural stability-resulting from ceramic reinforcement. The composite was fabricated using a controlled stir casting technique followed by mechanical testing and microstructural analysis. Results indicate improved strength, stiffness, and wear resistance due to effective load transfer from the ductile matrix to the ceramic reinforcement and grain refinement at the matrix reinforcement interface. This work demonstrates the suitability of Al-Li-Al2 O3 composites for aerospace, automotive, and structural applications requiring lightweight, high-strength materials.
