Al/SiC_NP and Al/SiC_NP/X nanocomposites fabrication and properties: A review

Abstract

Global requirement for minimum cost, high efficiency, and good grade materials has made a diversion in research from base alloys to composite materials, since the last five decades. In the case of metal matrix composites, aluminium metal matrix composites have been certified and steadily advanced due to properties such as high strength, low density, and high wear resistance. They are widely used in automobile industry, aircraft industry, structural applications, and many other defence systems. Researchers have observed that the addition of nano-size SiC NP reinforcements to aluminiumbased matrix yields superior properties and good bonding characteristics between matrix and reinforcements of nanocomposites. Along with silicon carbide particulate primary nano-reinforcements, researchers studied the properties of aluminium metal matrix nanocomposites with the addition of secondary reinforcements. These hybrid nanocomposites exhibited improved wear resistance. This article reviews the fabrication methods, mechanical properties, and tribological properties of aluminium-based hybrid metal matrix nanocomposites.

Dry sliding wear behaviour of ultrasonically-processed AA6061/SiCp nanocomposites

“…The reinforcement particles distribution in the metal matrix and grain refinement depended on the ultrasonic intensity. Wettability and interface bonding between nano-sized SiCp reinforcement and matrix material were good in the ultrasonic assisted casting method [30]. Ultrasonic apparatus was equipped with maximum output frequency of 20 kHz and maximum power of 2.4 kW.…”

Composites for electric vehicles and automotive sector: A review

“…The novel applications of aluminium matrix composites in various areas are presented in Figure 14. In order to improve the tribological and mechanical characteristics of AMCs, the frequently used reinforcements are alumina (Al2O3) [90], silicon carbide (SiC) [91,92], boron carbide (B4C) [93], titanium carbide (TiC) [94], graphite (Gr) [95], and carbon nanotubes (CNTs) [96]. Greater stiffness and strength, enhanced characteristics at elevated temperatures, lightweight, increased electrical conductivity, controlled coefficient of thermal expansion, enhanced abrasion and wear resistance are the advantages of composite materials J o u r n a l P r e -p r o o f 20 consisting of aluminium matrices when compared with traditional aluminium alloys [97,98].…”

A review on conventional and nonconventional machining of SiC particle-reinforced aluminium matrix composites

“…With the combined advantages of aluminum matrix materials and SiC reinforcement, SiC p /Al MMCs have been certified and are steadily advancing owing to their excellent properties such as high strength, low density, and high wear resistance. They are widely used in the automobile and aircraft industries, structural applications, and many other systems [5]. Since SiC p /Al composites consist of a metal matrix and a SiC reinforcement, different volume or weight percentage SiC in the matrix materials forms different SiC p /Al composites, e.g., 10% (mass fraction), 20% (volume fraction), 45% (mass fraction) and 65% (volume fraction) SiC p /Al matrix composites.…”
