Metal Matrix Nanocomposites (MMNCs) are a class of materials that consist of a metallic matrix embedded with nanoscale reinforcements. These reinforcements can be nanoparticles, nanofibers, or nanotubes, which significantly enhance the physical and mechanical properties of the base metal. The incorporation of these nanoscale elements aims to improve strength, hardness, wear resistance, and other properties while maintaining the desirable characteristics of the base metal.
