Abstract: Aluminum matrix composites (AMCs) reinforced with ceramic particulates have garnered substantial attention in aerospace and automotive applications owing to their superior strength-to-weight ratios and enhanced mechanical performance. This literature review synthesizes contemporary research on Al7075-based aluminum matrix composites reinforced with ceramic particles, including alumina (Al₂O₃), silicon carbide (SiC), iron oxide (Fe₂O₃), and titanium carbide (TiC). The review examined mechanical properties including hardness, tensile strength, yield strength, impact strength, and compressive strength reported across multiple experimental investigations. Particular emphasis was placed on stir casting as the predominant fabrication technique, analyzing critical process parameters such as stirring speed, pouring temperature, and holding duration. Microstructural characterization findings regarding particle distribution, interfacial bonding behavior, grain refinement mechanisms, and aggregation phenomena at varying weight fractions were systematically evaluated. A comparative analysis of reinforcement types and weight percentages across different studies revealed consistent trends in property enhancement, with optimal reinforcement concentrations typically ranging between 3-12 wt%. However, contradictions regarding particle agglomeration and porosity effects at higher weight percentages were identified, indicating knowledge gaps requiring further investigation. The review established that while ceramic reinforcement consistently improves hardness and tensile characteristics, understanding the complex relationships between processing parameters, reinforcement morphology, and resulting microstructures remains essential for optimizing composite design and engineering applications.
