“…The test materials were manufactured using a standard melt blend with nano SiC particles. The incorporation of Sb and SiC nanocomposites resulted in a decrease in the β-Mg 17 Al 12 phase present in the nanocomposite as well as a reduction in grain size [92]. Furthermore, additions of nanosized reinforcements of Sb and SiC improved the materials’ ultimate strength, yield strength, fatigue, and strain-hardening characteristics.…”

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.

“…When the test temperature increased to 220 • C, the dislocation began to break away from the weak pinpoint but was still pinned by the strong pinpoint. When the dislocation reached its peak temperature, an avalanche of nailing will occur, the original solid bonding strength between the matrix and enhanced phase begins to weaken with increasing temperature, and the relative slip between interfaces of adjacent particles is more likely to occur, resulting in friction and internal friction [33,34]. However, there are few slip systems in Mg with a hexagonal closest packed (HCP) structure at room temperature.…”

In order to effectively solve the problem of strength and ductility mismatch of magnesium (Mg) matrix composites, carbon nanotubes (CNTs) are added as reinforcement. However, it is difficult to uniformly disperse CNTs in a metal matrix to form composites. In this paper, electrophoretic deposition (EPD) was used to obtain layered units, and then the CNTs/Mg layered units were sintered by spark plasma sintering to synthesize layered CNTs/Mg composites. The deposition morphology of the layered units obtained by EPD and the microstructure, damping properties, and mechanical properties of the composite material were analyzed. The results show that the strength and ductility of the composite sample sintered at 590 °C were improved compared with the layered pure Mg and the composite sample sintered at 600 °C. Compared with pure Mg, the composites rolled by 40% had a much higher strength but no significant decrease in ductility. The damping properties of the CNTs/Mg composites were tested. The damping–test-temperature curve (tanδ~T) rose gradually with increasing temperature in the range of room temperature to 350 °C, and two internal friction peaks appeared. The damping properties of the tested composites at room temperature decreased with increasing frequency. The layered structure of the CNTs/Mg had ultra-high strengthening efficiency and maintained its ductility. The layered units prepared by EPD can uniformly disperse the CNTs in the composites.

“…So the magnesium metal matrix composites (Mg-MMCs) have been developed. Because of the micro-sized silicon carbide particle (SiC) possess of low density, highspecific strength, high specific stiffness, high wear resistance and low coefficient of thermal expansion, so the SiC serve as reinforcement in Mg matrix composites have been studied by many researchers [6][7][8][9]. Some researchers found that appropriate SiC addition can significant improved the hardness, tensile properties and corrosion resistant of the Mg alloys.…”

The laminated gradient of the SiC reinforced Mg-MMCs has been report few. In this paper, the laminated gradient structure of Mg-3Al-3Sn+xSiC alloys (x=0, 0.5, 1.0 and 2.0 wt %) were prepared via powder metallurgy and spark plasma sintering method, and the effects of different sintering rate (60℃/min, 70℃/min and 80℃/min) on the phase, morphology and corrosion resistance of as-sintered and rolled-state samples with laminated gradient structure are characterized. The results shows that, from the surface to core, the grain size of samples gradually decreased with the contents of SiC addition decreasing. Compared to the as-sintered samples, the micro-hardness of rolled-state reach to 105 HV, and the electrochemical test results shows that corrosion resistance of rolled states samples prepared at 70℃/min increased by 88 %, and the corrosion potential (Ecorr) value is -1.3162 VSCE, which is better than other samples; the samples prepared at 60℃/min increased by 36%, and the samples prepared at 80℃/min only decreased by 5%. It provides a new method to prepare the laminated gradient structure of magnesium alloy composites.
