      Abstract: TiC particle-reinforced aluminum matrix composites have attracted considerable research interest in recent years due to their low density, high specific modulus, excellent thermal stability, thermal conductivity, and wear resistance. The recent research progress of TiC particle reinforced aluminum matrix composites were reviewed, focusing on preparation methods, matrix alloying and heat treatment. The advantages and limitations of commonly used preparation methods were systematically discussed, and the role of matrix alloying in regulating interface bonding and microstructure was explored, along with its impact on the mechanical properties of the composites. Additionally, the evolution mechanisms of microstructure and element distribution during heat treatment were analyzed. Based on this, the research directions and key areas for the type of the composites were proposed, which can provide theoretical guidance and technical support for further development and application.
