Manufacturing and characterisation of magnesium composites reinforced by nanoparticles: A review

Abstract

Magnesium metal matrix composites (Mg-MMC) are versatile materials notable for their utilisation in automotive, aerospace, and manufacturing sectors due to their superior mechanical properties and high specific strength. Nanoparticle reinforcements at varying concentrations are used to improve the mechanical and tribological properties of the Mg alloy. In this paper, the effects of varying nanoparticles (namely silicon carbide, carbon nanotubes, titanium nanoparticles, and tungsten carbide) on different Mg alloys are discussed along with relevant manufacturing processes. From the literatures, Mg-MMCs are fabricated from AZ91 alloy with silicon carbide nanoparticle reinforcement of 1 wt-% composition, manufactured using ultrasonic-assisted stirring, which showed the best relationship in overall material properties over other nanoparticle reinforcements.

Microstructure and mechanical properties of friction stir welded AZ31 magnesium alloy reinforced with ZrB2

“…It shows the tensile strength of the base and welded samples of 0.5%, 1.0%, and 1.5% MMCs. The tensile strength and the percentage of elongation increase with an increase in the percentage of the addition of nanoparticles [32]. The trend is the same in both base and weld materials.…”

A Review on the Corrosion Performance of Magnesium Alloys in Biomedical Applications

“…These properties make magnesium ideal for many applications, including aircraft construction, shipbuilding, marine construction, automotive components, sporting goods, and medical devices. Magnesium is abundant in the Earth's crust, and magnesium alloys are readily available [2].…”
