Fabrication and mechanical properties of mesoporous silica nanoparticles reinforced magnesium matrix composite

Multiwall Carbon nanotubes (MWCNTs) are frequently attractive due to their novel physical and chemical characteristics, as well as their larger aspect ratio and higher conductivity. Therefore, MWCNTs can allow tremendous possibilities for the improvement of the necessarily unique composite materials system. The present work deals with the fabrication of Cu-Fe/CNTs hybrid composites manufactured by powder metallurgy techniques. Copper powder with 10 vol. % of iron powder and different volume fractions of Multi-Wall Carbon Nanotubes (MWCNTs) were mixed to get hybrid composites. The hybrid composites were fabricated by adding 0.3, 0.6, 0.9, and 1.2 vol.% of MWCNTs to Cu- 10% Fe mixture using a mechanical mixer. The samples were compressed under a load of 700 MPa using a hydraulic press to compact the samples. Sintering was done at 900°C for 2 h at 5ºC/min heating rate. The microscopic structure was studied using a Scanning Electron Microscope (SEM). The effect of CNTs on the mechanical and wear properties, such as micro-hardness, dry sliding wear, density, and porosity were studied in detail. The wear tests were carried out at a fixed time of 20 minutes while the applied loads were varied (5, 10, 15, and 20 N). SEM images revealed that CNTs were uniformly distributed with relative agglomeration within the Cu/Fe matrix. The results showed that the hardness, density, and wear rates decreased while the percentage of porosity increased with increasing the CNT volume fraction. Furthermore, the wear rate for all the CNTs contents increased with the applied load.

“…It is an important research objective of magnesium and its alloys to improve their mechanical properties. Literature review revealed that some researchers have attempted to enhance the mechanical strength of magnesium materials via particle reinforced magnesium matrix composites (PMMCs) [5][6][7][8][9]. Some processing technology for preparing PMMCs with different particle reinforcements have been investigated, such as Al 2 O 3 [10], SiC [11], TiB 2 [12] and so on.…”

Solid-phase synthesis was used to prepare AZ31/Al2O3 composites and the effect of Al2O3 particles on its microstructure and mechanical properties was investigated. The composites were characterised by optical microscopy, scanning electron microscopy, transmission electron microscopy, vickers hardness tester and electron universal strength tester. The results show that the grains of the composites are significantly refined and the mechanical properties increase obviously. While the content of Al2O3 particles is 2 wt-%, the hardness, ultimate tensile strength and elongation to failure reach the maximum of 85HV, 308 MPa, 6.83%, respectively. The addition of Al2O3 particles promotes the dynamic recrystallisation.
