This work presents the achievements of AMMCs fabricated by additive manufacturing in recent years, including manufacturing methods, microstructure, mechanical properties, and strengthening mechanisms.
Al-based metal matrix composites (AMMCs) have found enormous applications in the aerospace, automobile, and other structural applications. Compared with the conventional processes such as casting and powder metallurgy, AMMCs processed by additive manufacturing show a significant difference between microstructure and properties. This work presents the achievements of AMMCs fabricated by additive manufacturing in recent years, which is divided into six sections. Starting with the introduction, this work focuses on different fabrication methods such as composite powders and bulk material production. This is followed by discussing the microstructure in relation to the typical reinforcements and matrices, interface, and defects, and emphasizes the advantages and disadvantages compared with the unreinforced counterparts. The fourth part summarizes the recently obtained mechanical properties and the fifth part discusses the possible strengthening mechanisms and their connection with the mechanical properties. The last part is devoted to concluding the advantages, limitation, and outlook of the additively manufactured AMMCs. This review will provide a comprehensive picture of the processing-microstructure-property-strengthening mechanisms correlation of these composites.
