“…The details of microstructural, phase formation, and mechanical properties of the RZ5/TiB 2 composites in both as-cast and heat-treated condition is explained in our previous study. 26 A significant improvement in the mechanical properties is observed with an increase in wt.% TiB 2 in magnesium RZ5 alloy matrix. Heat treatment of the materials further enhances the mechanical properties of the RZ5/TiB 2 composites.…”

In the present study, the statistical analysis on tribological behavior of RZ5/TiB2 magnesium-based metal matrix composites is carried out using Taguchi design and analysis of variance (ANOVA) technique. Taguchi analysis using signal-to-noise ratio indicates that the sliding distance and wt.% TiB2 are the most significant factors in evaluating weight loss and coefficient of friction, respectively. The regression equation is formulated utilizing the ANOVA technique to study the output responses based on the input abrasive wear test experimental results. The regression equation is validated through a comprehensive study taking a series of abrasive wear tests and indicates the percentage deviation of regression modeling is in the range of ± 10%. The individual and combined effect of wear parameters on tribological behavior are investigated through the main effect plots and response surface plots. The micrograph of the worn surface of RZ5/TiB2 composites is studied using field emission scanning electron microscope (FESEM), indicating the formation of an oxide layer on the worn surface.

“…The detailed synthesis process of RZ5/TiB 2 Mg-MMCs is illustrated in our previous study. 26 As the as-cast magnesium RZ5 alloy and RZ5/ TiB 2 composites are relatively brittle, the mechanical properties can be improved by heat treatment of the material as per ASTM B661 -12. 27 setup.…”

“…Fang et al [12] illustrated that TiB 2 addition to Mg alloys aids for the grain refinement and also helps to enhance strength and ductility simultaneously. Meher et al [13] investigated the influence of TiB2 % on mechanical properties of TiB 2 /Mg MMC. The study revealed that 8% TiB 2 addition increase tensile strength of composite, besides further improvement was achieved through solution treatment of composites.…”

The current work aims to investigate the mechanical properties of rare oxide reinforced Mg alloy based MMCs. Magnesium matrix considered in the study is AZ91D alloy, whereas rare earth oxides reinforced were CeO2 and Y2O3. The Y2O3 particulate reinforcement percentage was varied from 1 to 3% in the steps of 1% to study its influence on mechanical properties of MMCs. Stir casting route was adopted to fabricate sample for study. Microstructure analysis illustrated the uniform distribution of particulate in matrix alloys. The obtained results revealed the enhanced mechanical properties such as tensile strength, yield strength, elongation and hardness of MMCs due to increased percentage of reinforcement. Fractography analysis of fracture surfaces demonstrated the microcracks and cleavage were dominant in pure alloy. While particle debonding, extensive plastics deformation were prominent in-addition to microcracks in MMCs.

“…However, their relatively low absolute strength and stiffness limit their further development, which can be overcome by strengthening using reinforcements, including ceramic and metallic fibers, particles, and carbon fibers. [3][4][5][6][7][8][9] Carbon nanotube (CNT) has received broad scientific and industrial attention in the past decades due to its excellent physical and chemical properties such as high elastic modulus, high strength, high thermal conductivity, low density and so on. CNT is a tube-like material that is made up of carbon with a diameter calculating on a nanometer scale.…”

This study aims to enhance carbon nanotube (CNT)-reinforced magnesium (Mg) matrix composites fabricated by spark plasma sintering (SPS). Ultrasonic treatment with organic solvent (DMAc) and dispersant (K2CO3) were used for the processes to make each CNT apart. Nano-order ceramic powders of zirconia (ZrO2) were found to be effective to keep uniform dispersion of CNT in Mg matrix. Low melting point metals such as Sn were added to fill voids and cracks in the composites. Post-SPS rolling was also employed aiming to improve the microstructures. The fabricated CNT-reinforced Mg composites were investigated on mechanical properties such as hardness and three-point bending strength to be related to the microstructures.
