Opportunities and Challenges for Metal Matrix Composites in the Context of Equipment Upgrading

Abstract

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.

An Insight into Mechanical and Metallurgical Behavior of Hybrid Reinforced Aluminum Metal Matrix Composite

“…'ey are regarded as the next generation of composite materials, capable of replacing single-reinforced AMCs [54]. Table 3 production process, uniformity of secondary phase dispersion, and appropriate interfacial bonding all influence the ultimate attributes of composite materials [9,60]. 'e percentage of reinforcement, type, size, numerous reinforcements, and Al matrix kinds are the critical criteria for enhancing physicomechanical, thermal, and wear and corrosion characteristics [61].…”

“…'is hybrid composite material has a wide range of uses, including aviation, defense, aerospace, and vehicles. Strategies will need to reduce their losses while boosting their advantages, just as they did with single reinforcement [15,60].…”
