In this paper, the application progress and development of metal matrix composites (MMCs) are reviewed from the perspective of industrialization strategy. The development process of MMCs in China is briefly summarized. The key technological breakthroughs in the main preparation methods of MMCs, such as in-situ synthesis, stirring casting, powder metallurgy, and pressure infiltration, are introduced. Typical engineering application cases of MMCs that promote equipment upgrading are listed. The development trend of MMCs in the next five to ten years is prospected. In view of the challenges posed to material technology by the development of equipment technology in the field of national defense and national economy, the development opportunities and prospects of MMCs in the civil-military dual-use market are analyzed. Moreover, to overcome the deficiency of industrialization technology and industrial environment, development suggestions are put forward, including consolidating national industrialization platforms and talent cultivation bases, increasing national investment, speeding up the construction of standards and database systems, and developing low-cost and high-quality material preparation technology.
