Nano and hybrid aluminum based metal matrix composites: an overview

Abstract

-Aluminium matrix composites (AMCs) are potential light weight engineering materials with excellent properties. AMCs find application in many areas including automobile, mining, aerospace and defence, etc. Due to technological advancements, it is possible to use nano sized reinforcement in Al matrix. Nano sized reinforcements enhance the properties of Al matrix compared to micro sized reinforcements. Hybrid reinforcement imbibe superior properties to aluminium matrix composites as compared with Al composites having single reinforcement. This paper is focused on overview of development in the field of Al based metal matrix with nano and hybrid aluminium based composites.

Synthesis of WS2/CNT hybrid nanoparticles for fabrication of hybrid aluminum matrix nanocomposite

“…Hybrid aluminum matrix nanocomposites have been considered to increase strength and toughness simultaneously, controlling the corrosion and lowering the costs in recent years. Some of the nano and micro particles used as a reinforcing agents in aluminum matrix are (SiC, Al 2 O 3 ), (graphite, SiC), (graphite, Al 2 O 3 ), (WS 2 , SiC) and (CNT, Al 2 O 3 ) [2][3][4][5]. Various methods have been used for fabricating the aluminum hybrid nanocomposites.…”

Quasi-Static and Plate Impact Loading of Cast Magnesium Alloy ML5 Reinforced with Aluminum Nitride Nanoparticles

“…The composites had a simultaneous increase in strength from 150 to 210 MPa and an elongation from 7% to 18%. Further improvements in structural parameters, including mechanical properties, can be ob55tained by heat treatments [7,8]. It was shown in [7] that the aging effect on the hardness of composites El21-AlN is significantly less compared with such an effect on the hardness of the initial alloy El21.…”

“…AlN nanoparticles also allow for the increasing of the heat and electrical conductivity of magnesium alloys [9]. The effect of heat treatment T6 on the improvement of mechanical properties of composites AZ91D/SiC is shown in [8].…”

Solid-State Recycling of Light Metal Reinforced Inclusions by Equal Channel Angular Pressing: A Review

“…The reinforcement fly ash particles from thermal power plant was also conducted at nano level of reinforcement to form Al matrix materials. The investigation of the nano fly ash particles (1 wt.% to 3 wt.%) causes in increase of AA2024 hardness of which reported as 75 Hv for 1 wt.% to 114 Hv for 3 wt.% [38]. Mechanical property such as compressive strength of nano fly ash/Al composite enhanced with increase in wt.…”
