“…Some of them have focused on Mg-matrix composites and achieved some enhancement in strength values. [4][5][6] It has been demonstrated that texture has a great effect on strength and ductility in Mg alloys. 7 Yamashita et al 8 reported that a remarkable gain in both ductility and strength of pure Mg and Mg9Al alloy could be achieved by grain refinement.…”

In this work, magnesium powders of different grain sizes were synthesized by mechanical milling for periods ranging from 0.5 to 30 h. Subsequent to milling, powders were consolidated by spark plasma sintering at 550 ℃ for 10 min. Before and after sintering, microstructural changes were investigated by analytical methods including X-ray diffraction (XRD), X-ray spectrometer, optical and electron microscopy. Analyses showed that nanocrystalline sizes were achieved by mechanical milling for milling times exceeding 5 h. Additionally, it was recognized that grain growth occurred during sintering, but to a limited extent. Mechanical test results displayed reasonable improvements in both compressive yield strength and hardness values with increasing milling times up to 5 h, where these reached their maximum values (245.5 MPa and 75.9 HV). The enhancement in these properties with increased milling time up to 5 h was attributed to both the extent of grain refinement and the formation of MgO together with incorporation of Fe particles, originating from the milling process, into the matrix. On the other hand, a substantial decrease in yield strength and hardness values in the samples milled in excess of 5 h were recorded, which in turn was related to the accompanying decline in bulk density of the samples. Microstructural analysis of the deformed samples revealed that grain size reduction suppressed twin formation, which elucidates the enhancement in ductility with decreasing grain size.

Coconut shell is an agricultural residue, usually disposed of through open burning. Toxic gases have been emitted from the open burning phase and can therefore be detrimental to human health and the environment. Thus, to reduce the risk of pollution, researchers have developed a new technology by using agro-wastes to produce biocomposites. Coconut shell powder (CSP) is a solid nonfood waste, which can be potentially exploited to reduce the usage of synthetic fiber. Coconut shell is also low-cost and low weight material that can be used to reduce the production cost of and fuel consumption for transportation. This review has focused on the research carried out on the CSP loaded into different types of matrices, highlighting the fundamental, mechanical, physical, and thermal properties of CSP composites. This article also provides critical review of the development for CSP composite and the summary of the results presented in the literature, focusing in the properties of CSP with polymeric matrices and the application design for economical products.

“…The metal matrix and nature of reinforcement is selected based on the nature of the properties expected for the composite. The last two decades witnessed abundant studies related to the effect of different types of reinforcements on metal matrix composites [6][7][8][9]. Based on the processing route, matrix composites exhibit a variety of properties.…”

“…Solid phase processes are commonly used for the manufacture of composites with fine microstructural features, which display enhanced strength properties. Powder metallurgy is one of the simplest modes of solid phase process to synthesize MMCs [6][7][8]. The most commonly used metal matrix materials are pure metals or conventional metallic alloys.…”

“…The properties of composites depend upon certain parameters, like the route in which the material is processed, the metal matrix used and the nature of the reinforcement. The mechanical properties can further be altered by secondary processing and heat treatment [6,12]. Therefore the selection of suitable matrix-reinforcement combination and the processing route are critical for procuring the optimum properties desired.…”

A composite based on Mg-3Zn-1Cu-0.7Mn alloy reinforced withAl 2 O 3 was synthesized using blend-press-sinter powder metallurgy route and hot extruded at 400 o C. The study concentrates on investigating the effectiveness of alumina as reinforcement and analyzing the effect of stress relieving on the mechanical and microstructural properties of the composite. The results of the study indicate that the ultimate tensile strength, yield strength and fracture strain of the composite was increased in the composite compared to the pure Mg metal. It is also proved that stress relieving has a significant role on the ultimate tensile strength and fracture strain in the composite.
