A review on mechanical properties of aluminium-based metal matrix nanocomposites

Industrial production today requires new improved materials to meet market demands, which leads to the production of new materials with improved properties. One kind of response to those requirements is the development of metal matrix composites (MMCs) with the aim of obtaining materials with better properties when compared to conventional metals and alloys. Nowadays, metal matrix nanocomposites (MMnCs) are being increasingly investigated due to the possibility of achieving better machinability, high fracture toughness and improved ductility when compared to conventional composites. Considering the pace of development and the huge perspective of different classes of materials, this research aims to provide insight into the mechanical properties of aluminium nanocomposites. Aluminium nanocomposites are attracting a lot of attention due to their high strength-to-weight ratio, wear resistance and low costs, when compared to matrix alloy. In this paper, an attempt is made to review other research reports and make a connection between the characteristics of the microstructure and the mechanical properties, which are dependent on the method of fabrication and type and content of reinforcement.
