Additive Manufacturing of Advanced Metallic Composite Materials

Dear Colleagues,

Metal matrix composites (MMCs) have gained significant attention due to their high strength-to-weight ratio, good wear resistance, and improved thermal and mechanical properties. These materials are widely used in the aerospace, automotive, biomedical, and energy industries, among others. However, conventional manufacturing processes often face limitations in producing complex geometries and achieving a uniform distribution of reinforcement particles.

Additive Manufacturing (AM) is an emerging and advanced technology for fabricating metallic composite materials. AM processes build components layer by layer, providing high design flexibility and better control over the microstructure. This technology also allows for the fabrication of complex shapes that are difficult to produce using conventional manufacturing methods. The addition of reinforcement particles, fibers, or secondary phases into metallic matrices through AM provides new opportunities to tailor microstructures and improve material performance.

Several scientific and technical challenges remain, such as achieving uniform reinforcement distribution, controlling porosity and interfacial reactions, understanding rapid solidification behavior, and optimizing processing parameters. Addressing these challenges requires combined efforts in advanced manufacturing techniques, microstructural characterization, computational modeling, and materials design.

This Special Issue aims to provide a platform for researchers to present recent advances in the design, processing, characterization, and applications of additively manufactured metallic composite materials. We welcome original research articles, review papers, and communications that improve the understanding and performance of these advanced materials. Topics of interest include, but are not limited to, the following:

• Additive manufacturing processes for metal matrix composites;
• Microstructure evolution and phase transformations during AM;
• Mechanical, tribological, and functional properties of AM composites;
• Interface engineering between matrix and reinforcement phases;
• Modeling and simulation of AM processes and microstructure development;
• Process optimization and defect mitigation in AM;
• Post-processing treatments and property enhancement;
• Machine learning for additive manufacturing and metal matrix composites;
• Industrial applications of additively manufactured metallic composites.

This Special Issue aims to bridge the gap between materials design, advanced manufacturing technologies, and industrial applications, contributing to the development of high-performance metallic composite materials for next-generation engineering systems.
