“…There are several drawbacks of Mg alloys due to limited thermal stability, highly sensitive to thermal expansion, high corrosion rate, and low performance at high temperatures that make them unsuitable for many applications. [89][90][91][92] The benefits of hybrid composites are as follows: (a) microstructural and mechanical properties have been enhanced; (b) good for mass production; and…”

High-performance lightweight materials give rise to a demand for magnesium-based composites. Magnesium metal matrix composites have found extensive applications in the aerospace and automotive industries due to their remarkable mechanical properties. Limitations in dispersion, strength, and interface strength of magnesium-based composites are seen through the addition of some hybrid reinforcements and different fabrication techniques. In this regard, previous studies have demonstrated the ability of various reinforcements such as graphene, carbon nano tubes, silicon carbide, and titanium carbide to a magnesium matrix for the enhancement of its metallurgical properties. There are still several challenges in the development of magnesium metal matrix composites, such as non-homogeneous distribution, poor creep resistance at elevated temperatures, limited cold work ability, and low corrosion resistance. The challenges that need to be overcome and suggestion for improving the wear resistance and frictional properties of magnesium metal matrix composites were studied and discussed. This review evaluates the importance of different reinforcement percentages as well as the development of magnesium metal matrix composites. The different types of fabrication techniques that are well suited to overcome the challenges of poor dispersing, non-homogeneous distribution, interfacial problems, and poor wettability are discussed. Microstructure analysis, the agglomerating effect, and matrix bonding strength are also discussed. The challenges and future scope of research are discussed for the demonstration of the importance of more scientific studies in magnesium metal matrix composites.

For a varsity of application, materials are demanded with high damping that can lower fundamental natural frequencies, and composites offer widespread options towards designing space structure with lightweight which are controlled effectively. Damping fixtures were made with lightweight composites, for the purpose of transporting aerospace components from one place to another. This present work investigates the damping characteristics of lightweight magnesium-based composite (AZ31+x%Si3N4), subjected to vibration. The composite cantilever beam is excited using an impact hammer and the vibrations generated are recorded using a data acquisition system. The damping properties are related to the density and microstructure of the fabricated composites. Results show that the damping factor changes with higher reinforcement of Si3N4 ceramic particulates and the microstructure obtained during casting have an influence on the damping performance.

“…Owing to light weight property, high strength to weight ratio, durability, toughness, energy efficiency and performance, composites acknowledged worldwide. 1,2 Composite materials are multiphase engineering materials architect with amalgamation of two or more than two divergent materials encompassing dissimilar composition and properties which enable to produce exceptional materials without altering chemical composition and original identities of parent material. Thus, the composites are product of well-connected physically blended materials rather a product of any chemical reaction.…”

Flourishing trend of aerospace and automobile applications endlessly demand for significantly higher encouraging performance lightweight materials. Potentially Magnesium got limelight for having lightweight physical property and thus has great potential to energize mechanical property by making its composites. Therefore, magnesium composite was fabricated by incorporating multi-walled carbon nanotubes (MWCNTs) as reinforcement into magnesium matrix at volume percentages 10, 20 and 30, respectively through friction stir processing (FSP). Furthermore, the effect of MWCNTs was investigated and validated through various characterizations. The X-ray diffraction (XRD) investigation ensured the existence of parent phases of materials. The mechanical properties of MWCNT/Mg composites such as tensile strength and micro hardness were investigated and found optimum results at 20 vol% MWCNTs. The optimum upsurge in tensile strength attained was twice relative to pure magnesium. Moreover, the wear test was conducted to analyse the wear behaviour. Since the grain growth was obstructed by MWCNTs reinforcement and encouraged to enrich grain refinement, thus the wear resistance was improved. However, the mechanical properties deteriorated beyond 20% due to clustering of reinforcement revealed from fracture study.
