Special Issue Information

Dear Colleagues,

We are pleased to invite you to contribute research papers and review articles for this Special Issue, entitled “Novel Metal Matrix Composite Materials”. Metal matrix composites, which integrate a metallic base with reinforcing phases (e.g., ceramics, carbon fibers, or nanoparticles), represent a transformative advancement in materials science. The scientific significance of novel metal matrix composites lies in their potential to revolutionize industries demanding lightweight, high-performance materials. By advancing novel metal matrix composites, scientists not only push the frontiers of material science but also directly contribute to sustainable technological progress.

This Special Issue aims to advance the understanding and innovation of metal composites by exploring cutting-edge strategies in material design, fabrication technologies, performance optimization, and specific applications. It seeks to address critical challenges of metal composites in applications relating to catalysis, energy, sensing, electromagnetic wave absorption, and other fields.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  1. Material design and innovation.
  2. Advanced manufacturing techniques.
  3. Special physical and chemical properties.
  4. Mechanical and functional properties.
  5. Applications in catalysis, energy, sensing, electromagnetic wave absorption, etc.

 We look forward to receiving your contributions.

In this study, titanium alloy-based composites reinforced with carbon nanotubes (CNTs) and graphene (Gr) were fabricated via spark plasma sintering (SPS). The effects of CNT and Gr reinforcements on the microstructure, density, hardness, and tribological properties of the composites were systematically investigated. The results revealed that CNTs and Gr were dispersed within the Ti alloy matrix. All composites exhibited high relative densities about 99%, confirming the strong densification capability of the SPS process. The incorporation of CNTs and Gr significantly enhanced the mechanical performance of the composites. The maximum hardness values of 445.8 HV and 430.5 HV were obtained for CNT/Ti and Gr/Ti composites containing 3 vol.% reinforcement, corresponding to improvements of 34% and 30%, respectively, compared with the unreinforced Ti alloy. Tribological tests further revealed notable reductions in the coefficient of friction and wear rate for both CNT/Ti and Gr/Ti composites. These enhancements are attributed to the formation of a lubricating tribo-film composed of carbonaceous species and oxide particles (TiO2, Al2O3) on the worn surfaces. Among the two reinforcements, the obtained results indicated that CNTs are more effective in enhancing hardness, whereas graphene provides superior improvement in wear resistance of Ti alloy-based composites. Overall, this work demonstrated that the combination of Ti alloys with nanocarbon reinforcements is an effective approach to simultaneously enhance their mechanical and tribological performance.
