英文摘要:

      Particle-reinforced aluminum matrix composites have excellent specific stiffness, specific strength, fatigue-resistance, heat-resistance and radiation shielding, etc., making them important engineering materials that are widely used in aerospace, military, electronic and automotive applications. In such materials, the structure and pro-perties of the reinforcement-matrix interface significantly affect their bulk properties. The typical fabrication routes and applications of particle-reinforced aluminum matrix composites are discussed, with particular focus on the interfacial characteristics, including the structure, cohesion, wetting behavior, and thermal stability of the reinforcement-matrix interfaces, and their effect on bulk properties. The impacts of various factors in the fabrication process on the interfacial properties are also discussed. It is proposed that micro-/nano-scale measurements combined with site-specific electron microscopic analysis may provide important implications on the correlation between the nature of the interface and the properties in particle-reinforced aluminum matrix composites.
