Utilizing Low‐Cost Eggshell Particles to Enhance the Mechanical Response of Mg–2.5Zn Magnesium Alloy Matrix

Abstract

The search for lightweight high-performance materials is growing exponentially primarily due to ever-increasing stricter environmental regulations and stringent service conditions. To cater to these requirements, the use of lowcost reinforcements has been explored in the Mg matrix to develop Economically Conscious Magnesium (ECo-Mg) composites. In this study, eggshell particles (3, 5, and 7 wt%) reinforced Mg-Zn composites are synthesized using blend-press-sinter powder metallurgy technique. The results reveal that the addition of eggshell particles enhances microhardness, thermal stability, damping, and yield strength with an inappreciable change in the density. In particular, Mg2.5Zn7ES composite do not ignite till %750 C. The overall combination of properties exhibited by Mg-Zn-ES composites exceeds many of currently used commercial alloys in the transportation sector. An attempt is made, in this study, to interrelate microstructure and properties and to study the viability of compression and ignition properties with a comparison to commercially used Mg alloys.

The Potential of Magnesium Based Materials in Mandibular Reconstruction

“…Further, in comparison to commercially used orthopedic implants like titanium alloys, stainless steel, and cobalt-chromium (Co-Cr) alloys, Mg possesses considerably lower elastic modulus matching the elastic modulus of the bone (trabecular/cancellous bones) which aids in eliminating/decreasing any possible stress shielding effects at the bone/implant interface and facilitate new bone formation [64][65][66][67]. In addition, Mg 2+ is the fourth most abundant cation involved in many chemical reactions in our body, hence establishing its prime importance in the metabolism process [68]. Also, Mg assists in several antibody formations, alleviating tension in the blood vessels and thereby aiding in regulated muscle contractions.…”

“…The reinforcement phases like hydroxyapatite, tricalcium phosphate, fluorapatite, and calcium polyphosphate could also be used in the Mg matrix either individually or in a hybrid form to develop biodegradable magnesium matrix nanocomposites with enhanced mechanical properties and controlled degradation rate. Presence of calcium in the form of supplements could also assist with osteoblast activity, leading to easier bone remodeling activity [68,110]. Prakash et al [111] studied the effect of Si and HA addition to the corrosion resistance and in vitro bioactivity behavior of Mg-Zn-Mn alloy using MG-63 osteoblast cells.…”

“…Biosafety and biocompatibility: Elements such as Al and Be have been identified as neurotoxic [68] and should preferably be avoided for alloying, as they are not suitable candidates for biomedical applications.…”

Effect of Uncarbonized Eggshell Weight Percentage on Mechanical Properties of Composite Material Developed by Electromagnetic Stir Casting Technique

“…However, beyond 4 % of eggshells reinforcement inverse effect was observed. Parande et al [17] have fabricated Mg-2.5 Zn magnesium alloy matrix based composite using eggshells as reinforcement. Results of experimental studies show that mechanical and thermal properties of fabricated composite were improved.…”

Enhancing Mechanical Response of Monolithic Magnesium Using Nano-NiTi (Nitinol) Particles

“…Structure-property evaluations are detailed in the current study.Mg matrix greatly enhances the mechanical properties such as strength and stiffness. Thus, magnesium matrix composites (MMCs) are widely being used due to their better mechanical properties as compared to pure metals [1,[7][8][9][10]. In addition, many novel and advanced materials have been developed based on the various types of matrix and reinforcements.…”
