Abstract: High-strength aluminum alloys are widely used in industries such as aerospace, automotive, and defense due to their excellent strength-to-weight ratio and good mechanical properties. However, optimizing their mechanical properties while maintaining cost-effectiveness and processing efficiency remains a significant challenge. This paper investigates the fundamental aspects of microstructure control and mechanical property optimization in high-strength aluminum alloys. It focuses on the influence of alloy composition, heat treatments, and processing techniques on the material's strength, ductility, toughness, fatigue resistance, corrosion resistance, and wear properties. The paper also explores the role of advanced experimental techniques, such as metallographic analysis, mechanical testing, and X-ray diffraction (XRD), in characterizing the microstructure and mechanical performance of these alloys. Moreover, it emphasizes the importance of microstructure refinement, solid solution strengthening, precipitation hardening, and the addition of specific alloying elements in optimizing the alloy's overall performance. The review provides valuable insights into the key strategies for designing high-strength aluminum alloys with enhanced mechanical properties, focusing on their applications in high-performance engineering fields.
