Special Issue Information

Dear Colleagues,

Following the success of the first edition of the Nanomaterials Special Issue “Metal-Matrix Nanocomposites and Their Applications”, in which a total of 8 papers were published (https://www.mdpi.com/journal/nanomaterials/special_issues/metal_matrix_nanocomposite), we are delighted to announce the launch of a second edition.

There is increasing interest in the development of metal matrix nanocomposites since the addition of nanoparticles, nanowires, nanotubes or nanolayers can lead to an extraordinarily high strength-to-weight ratio and enhanced mechanical, physical and chemical properties over conventional materials. For metal matrix nanocomposites, critical challenges involve the dispersion of nano-reinforcing phases, the control and optimization of interface structure, the theoretical mechanisms of mechanical and functional properties, etc. Furthermore, their excellent and tailorable properties make them very attractive for a variety of applications, such as aerospace, transportation, electronics, thermal management, etc.

This Special Issue will highlight the latest advances in metal matrix processing, interface modification, microstructure characterization, properties and usage in a myriad of applications.

Original theoretical and experimental research articles, communications and reviews are welcome. Research topics of interest include (but are not limited to) the following:

  • Metal matrix nanocomposites (aluminum, magnesium, titanium, copper, or iron matrix, etc.);
  • Layered nanocomposites (multiple nanolayers composed of various materials or nanolayer sandwiches bonded to a metal matrix core);
  • Nanoscale interface modification;
  • Processing;
  • Microstructure characterization;
  • Properties;
  • Application.

We look forward to receiving your contributions.

Diamond/aluminum composites have attracted significant attention as novel thermal management materials, with their interfacial bonding state and configuration playing a crucial role in determining their thermal conductivity and mechanical properties. The present work aims to evaluate the bending strength and thermal conductivity of CNT-modified Ti-coated diamond/aluminum composites with multi-scale structures. The Fe catalyst was encapsulated on the surface of Ti-coated diamond particles using the solution impregnation method, and CNTs were grown in situ on the surface of Ti-coated diamond particles using the plasma-enhanced chemical vapor deposition (PECVD) method. We investigated the influence of interface structure on the thermal conductivity and mechanical properties of diamond/aluminum composites. The results show that the CNT-modified Ti-coated diamond/aluminum composite exhibits excellent bending strength, reaching up to 281 MPa, compared to uncoated diamond/aluminum composites and Ti-coated diamond/aluminum composites. The selective bonding between diamond and aluminum was improved by the interfacial reaction between Ti and diamond particles, as well as between CNT and Al. This led to the enhanced mechanical properties of Ti-coated diamond/aluminum composites while maintaining acceptable thermal conductivity. This work provides insights into the interface’s configuration design and the performance optimization of diamond/metal composites for thermal management. Full article
