Aluminum or Its Alloy Matrix Hybrid Nanocomposites

Abstract

Aluminum or its alloys are widely used in automobile, aerospace, and marine due to their low density, good ductility, low cost, corrosion resistance etc. However, aluminum has several pit falls viz. poor strength, abrasion and wear resistance etc. These pit fall of aluminum can be improve by reinforcement of nanomaterials in the pure metal or alloy. Various types of nanomaterials can be used for the fabrication of light-weight aluminum/alloy matrix nanocomposites for high specific strength, improved wear and abrasion property, better corrosion resistance etc. Recently, there is a significant research interest for the fabrication of nanocomposites by using more than one reinforcing materials. This article presents an overview of various reinforcement materials used for the fabrication of aluminum or its alloy matrix based hybrid nanocomposites. Brief overview of metal matrix and specifically aluminum matrix nanocomposites are included in the manuscript. Various processing routes for the fabrication of hybrid nanocomposites are explained. Properties of hybrid nanocomposites with respect to the nano-reinforcement types, reinforcement concentration, morphology and microstructure are discussed. Further, potential applications and future trends of aluminum or its alloy matrix hybrid nanocomposites are presented. Finally, the article has been concluded with several future scopes of research in the area of aluminum/alloy matrix based hybrid nanocomposites.
