Metal matrix nanocomposites （MMNCs） are made of nano-sized reinforcements of metals or nonmetals well-distributed in metal or alloy matrix. These composites exhibit special microstructure feature and possess excellent physical, mechanical and chemical properties owing to their combination of metal with nanophases. Metal matrix nanocomposites （MMNCs） have raised considerable interest and become one of novel nanocomposites and new metal functional materials in recent years. In this paper, new research achievements of block metal matrix nanocomposites are summarized. The property, preparation and classification of these composites are also generalized. Moreover, the application prospects for metal matrix nanocomposites are discussed.
