Abstract:

Preparation of metal matrix composites using molecular-level mixing process can realize uniform distribution of second-phase particles in the matrix and trong interfacial bonding between second-phase particles and matrix， therefore significantly improving the mechanical properties of as-fabricated composites. This method has attracted great attention from more and more researchers in recent years. This paper reviews the research progress of metal matrix composites fabricated by molecular-level mixing process at home and abroad. The technology and performance characteristics of various metal matrix composites fabricated by this method are combed， and the development trend of metal matrix composites preparation research is prospected.
