Characterization of microstructure, mechanical properties and corrosion response of aluminium-based composites fabricated via casting—a review

Despite the desirable properties possessed by aluminium, the development of aluminium matrix composite (AMC) has been useful in solving challenges arising from the selection of appropriate materials for most advanced engineering applications. Most of these challenges are resolved through the introduction of second- and/or third-phase particles into the matrix of aluminium. Conventional reinforcements, which include agro-based waste, nitrides, borides and carbides of some specific metals, were observed to improve the microstructural, mechanical and corrosion properties of AMCs fabricated through several casting techniques. The performance exhibited by these AMCs is, however, dependent on the processing technique utilized during the addition of the reinforcement to the matrix of aluminium. This paper attempts to review various fabrication routes, effects of different reinforcements, general properties and application of aluminium matrix composites in several industries.
