“…Yousefpour et al 72 reported that an increase in FSP passes provided a more homogeneous distribution of the particles and increased the hardness. Gupta et al 82 investigated the effect of CeO 2 with different particle (nano, micron, submicron) sizes on the hardness of Mg matrix composites. It was reported that nanoparticle-reinforced composite exhibited the highest hardness due to the smallest grain size.…”

“…However, FSP-2 sample had lower strength than that of base metal due to orientation softening and nonuniform distribution of reinforcement particles. Gupta et al 82 reported that CeO 2 particles caused grain refinement and increased strength due to the pinning effect for Mg-CeO 2 composites. The maximum strength was reported for nanoparticle addition.…”

“…Different researchers reported that the Orowan mechanism contributed to the increase in yield strength. 44,45,53,[60][61][62]82 Borodianskiy et al 44 reported that the motion of dislocations was hindered by reinforcement particles due to the formation of Orowan loop, which leads to an increase in strength. As a result, the Orowan strengthening was identified as an important mechanism for the increase in yield strength.…”

Magnesium (Mg), with a density of two-thirds of aluminium (Al) and one-fourth of steel, has become one of the most attractive materials for automotive and aerospace industries owing to the obligation to reduce fuel consumption and gas emissions. However, the poor mechanical property of Mg is one of the most significant barriers to its widespread use. The most widely used method to increase the use potential of Mg is the development of Mg matrix composites. This review focuses on the mechanical properties of recent Mg matrix composites. The effect of different reinforcement materials on the mechanical behaviour and failure mechanisms of Mg matrix composites was evaluated in detail.

Deep cryogenic treatment has shown promise as a facile method of increasing the characteristics of many materials including alloys of iron, aluminum, and magnesium. However, there have not been any prior studies on its effect on the microstructure and thermal and mechanical properties of magnesium-based nanocomposites. In this study, a Mg/2wt.%CeO2 nanocomposite was processed using disintegrated melt deposition processing coupled with hot extrusion, followed by cryogenic treatment in liquid nitrogen for 24 h. The characterization results show increases in density (reduction in porosity), ignition temperature, compressive yield strength, compressive ductility, and microhardness. This study, for the first time, shows the significant relevance of deep cryogenic treatment in enhancing an array of properties of a magnesium-based nanocomposite that may be catalytic in improving its application spectrum.

The present study attempted for the first time an investigation on the effect of deep cryogenic treatment in liquid nitrogen (LN) on magnesium–cerium oxide (Mg/2wt.%CeO2) composites containing equal amounts of different length scales (micron and nanosize) cerium oxide (CeO2) particles. The disintegrated melt deposition method was used to synthesize Mg-2CeO2 micro- and nanocomposites, followed by hot extrusion as the secondary processing. Further liquid nitrogen treatment was performed at a cryogenic temperature of −196 °C. The combined effects of cryogenic treatment and reinforcement length scale on physical, mechanical, and thermal behaviors were studied. The results indicate that LN-treated micro- and nanocomposite samples exhibit, in common, a reduction in porosity, similar grain size, and a limited effect on the original texture of the matrix. However, microhardness, 0.2% Compressive Yield Strength (CYS), failure strain, and energy absorbed increased for both micro- and nanocomposite samples. Overall, results clearly indicate the capability of deep cryogenic treatment with LN to positively diversify the properties of both micro- and nanocomposite samples.
