Fe3O4 Nanoparticle-Reinforced Magnesium Nanocomposites Processed via Disintegrated Melt Deposition and Turning-Induced Deformation Techniques

Abstract

Magnesium nanocomposites, with nano-scale ceramic reinforcements, have attracted a great deal of attention for several engineering and biomedical applications in the recent past. In this work, superparamagnetic iron oxide nanoparticles, Fe3O4, with their unique magnetic properties and the ability of being bio-compatible and non-toxic, are reinforced to magnesium to form Mg/(1, 2, and 3 wt %) Fe3O4 nanocomposites. These nanocomposites were fabricated using the conventional disintegrated melt deposition (DMD) technique followed by extrusion. Further, the materials were also processed using the novel turning-induced-deformation technique where the chips from turning process are collected, cold compacted, and hot extruded. The materials processed via the two techniques were compared in terms of microstructure and properties. Overall, the Mg/Fe3O4 nanocomposites, processed via both routes, exhibited a superior property profile. Further, the turning-induced deformation method showed promising results in terms of improved properties of the nanocomposites and serves as a great route for the recycling of metallic materials.

The Promise of Turning Induced Deformation Process for Synthesizing Magnesium Based Materials with Superior Mechanical Response

“…Results and properties of Mg materials from previous works [18,24,25] concerning the TID method were consolidated and discussed in this review.…”

“…Considering that recent TID efforts specifically stored Mg turnings in such a manner as to avoid contamination and oxidation [24,25], and the knowledge that oxide size affects ductility [18], this can explain the difference in reported ductility levels and thus overall material performance.…”

Introductory Chapter: An Insight into Fascinating Potential of Magnesium

“…Ever since upliftment of the ban on magnesium by FAA [13], there is an ever-increasing demand for highperformance magnesium alloys for reducing weight in aircraft structures such as interior components, fuselage structures, gearboxes, aero engine frames, helicopter transmissions, covers and components, flight control systems, electronic housings, and aircraft wheels [14]. With advancement in the alloy design and material development, for the abovementioned as well as other applications in both commercial and military aircrafts, advanced higher-performance magnesium alloys and composites that are also ignition-resistant or ignition proof and corrosion-resistant suit the requirement of the aviation industries and can help in achieving sustainability and protecting the environment [8,[15][16][17].…”

Production and Properties of Light Metal Matrix Nanocomposites

“…In another work by Manoj Gupta's group, pure magnesium was reinforced with superparamagnetic Fe 2 O 3 nanoparticles to generate a material suitable for biomedical degradable implants [14]. The material was produced by the DMD process with subsequent extrusion and alternatively by a process where chips produced during turning are collected, compacted, and extruded.…”
