Machining the growth of the manufacturing sector has led to an increased utilization of aluminum metal matrix composites (AMMCs). These composites have gained significant interest worldwide, particularly in the automotive, architectural, and aerospace sectors, due to their exceptional mechanical and tribological properties. AMMCs exhibit high specific strength, improved strength to-weight ratio at high temperatures, and superior wear resistance compared to the matrix phase alone. To enhance the metallurgical and mechanical properties of the base matrix, various types of particulate reinforcements such as SiC (silicon carbide), Al₂O₃ (alumina), B₄C, TiC, and ZrSiO₄ are employed. To fabricate AMMCs, authors have employed different manufacturing processes including solid-state techniques like powder metallurgy and liquid-state processes such as stir casting, compo-casting, squeeze casting, and in-situ casting routes. Among these methods, stir casting is the most cost-effective and straight forward approach for producing AMMCs. This article provides a comprehensive explanation of the process involved in fabricating AMMCs using Al-7175 as the matrix material, with B₄C and SiC as the reinforcements, via the stir casting process.
