Abstract
SiCp/Al-Si composites have advantages such as high specific strength,specific stiffness,specific modulus,good thermal conductivity,electrical conductivity,wear resistance,and dimensional stability,and thereby they are used as structural and functional materials in the fields such as space engineering,electronic packaging,transportation and precision instruments.The hot research topic about it mainly focus on interface structure control,strengthening mechanisms and performance control.In the SiCp/Al-Si composites,there are interfaces between reinforcement and matrix,precipitation phase and matrix,and precipitation phase and reinforcement phase.These interfaces are influenced by various factors,resulting in various interface reactions and products,and the interface structure and binding state are complex and diverse.Based on this,this article reviews the influence and control of preparation process,matrix alloy composition and SiCp surface modification on the interface structure of the SiCp/Al-Si composites,and summarizes the factors that affect their mechanical properties and the research status of strengthening mechanisms.Finally,it prospects the future development and research directions of the composites.
