Special Issue Information

Dear Colleagues,

Metal Matrix Composites (MMCs) represent promising advanced materials that have garnered significant attention in various industrial sectors due to their exceptional mechanical properties and tailored functionality.

MMC design involves incorporating one or more reinforcing phases, such as ceramic, carbon, or other metallic materials, into a metal matrix. This strategic combination allows engineers to tailor the material's properties to meet specific requirements, including improved strength, stiffness, thermal conductivity, and wear resistance. The selection of reinforcement materials, their volume fraction, and distribution within the matrix are critical factors in optimizing the final composite's performance.

The development of MMCs encompasses several fabrication techniques, including powder metallurgy, in situ synthesis, and various casting methods. Each method offers unique advantages and challenges, influencing the resulting material's microstructure and properties. Advanced processing technologies, such as high-energy ball milling, spark plasma sintering, and rapid solidification, have enhanced the homogeneity and performance of MMCs.

In this Special Issue, we welcome articles focusing on producing metal matrix composites through processes such as powder metallurgy, casting, and additive manufacturing. Microstructural characterization and determination of its relationship with final mechanical properties are also objectives of this Special Issue due to the importance of this knowledge for their implementation. Thus, researchers are invited to propose original investigations involving recent advances in the design, production, and characterization of metal matrix composites.

This study systematically investigates the synergistic corrosion resistance enhancement mechanisms in aluminum matrix composites (AMCs) through the combined implementation of equal channel angular pressing (ECAP) and Ti3C2Tx MXene reinforcement. The results demonstrate that ECAP treatment significantly refines the microstructure, reducing grain sizes to an average of 8.7 µm after three passes, while improving mechanical properties such as hardness by 40.6–45.1%. Additionally, the incorporation of Ti3C2Tx enhances corrosion resistance by establishing a physical barrier that impedes the diffusion of corrosive mediators and prevents localized corrosion. Electrochemical tests reveal that the composite subjected to three ECAP passes exhibits the lowest corrosion current density (Icorr) and a remarkable 3.4-fold increase in charge transfer resistance (Rct) compared to untreated material. These findings highlight the potential of synergistically integrating ECAP and Ti3C2Tx to develop high-performance AMCs with enhanced mechanical strength and corrosion resistance, offering significant implications for applications in marine equipment, aerospace, and new energy vehicles.
