Abstract: Particulate reinforced metal matrix composites (MMCs) are widely used in many industries. With the development of nanotechnologies, the particulates scales down to the nano-level to enhance MMCs. MMCs with nano-sized reinforcements are termed as metal matrix nanocomposite (MMNCs). MMNCs have shown promising properties. Many researchers are using different methods to fabricate MMNCs. In this paper, some commonly used methods used to fabricate MMNCs are introduced including: powder metallurgy, casting, rapid solidification and in-situ fabrication. The enhancing mechanism of MMNCs is discussed. The properties obtained by different methods are illustrated. Some unsolved problems are also listed.

Keywords: metal matrix nanocomposites; MMNC; nanoparticulate; powder metallurgy; casting; in-situ fabrication; composites; nanoparticles; nanotechnology; rapid solidification.
