A Review on the Fabrication Techniques of Aluminium Matrix Nanocomposites

Abstract

In recent years, metal matrix composites have been considered as materials that offer better mechanical properties compared to conventional alloys. Recently, the developments of metal matrix nanocomposites (MMNCs) have become more attractive in various applications. However, the synthesis of MMNCs by conventional casting method has shown a limitation due to low wettability of the reinforcement phase by the molten metal. This paper is aimed at reviewing the best result techniques to fabricate the aluminium matrix nanocomposite (AlMNCs). However, each of these techniques has their own advantages and disadvantages. This review concludes powder metallurgy (PM) as the best technique for mass production and cost effectiveness.

“…FSP has been developed for use with aluminium alloys, with the goal of high-strain-rate processing [3]. FSP is a fast method with simple processing and low cost to in situ synthesizes particulate-reinforced composites especially in aluminium alloy [4][5] as the composite materials promote better properties including mechanical properties [6]. FSP enhanced the distribution of the reinforced particles which resulting more homogeneous and thermodynamically more stable in metallurgical properties as the matrices and reinforcement have a strong interfacial bonding [7].…”
