“…Figure 22 shows the evolved microstructure of CNT-AZ31 nanocomposites produced using the disintegrated melt deposition technique followed by hot extrusion. As seen, the formed Mg 17 Al 12 particles are distributed at or along α phase boundaries and give rise to the grain refinement of Mg matrix [148]. The formation of the mentioned intermetallics enhances the mechanical properties of CNT-Ti matrix nanocomposites through guaranteeing the suitable wetting between the matrix and nanotubes.…”

“…It can significantly prevent the microscale cavities which form at the Ti/CNT interfaces and contribute to improved mechanical properties [12]. Additionally, the formed intermetallics can improve the mechanical properties of the nanocomposites through the restriction of mechanical deformation [148]. The formation of a clean interface with no impurity or defect is shown to improve the mechanical properties [144].…”

Abstract:The inclusion of carbon nanotubes (CNTs) into metallic systems has been the main focus of recent literature. The aim behind this approach has been the development of a new property or improvement of an inferior one in CNT-dispersed metal matrix nanocomposites. Although it has opened up new possibilities for promising engineering applications, some practical challenges have restricted the full exploitation of CNTs' unique characteristics. Non-uniform dispersion of CNTs in the metallic matrix, poor interfacial adhesion at the CNT/metal interface, the unfavorable chemical reaction of CNTs with the matrix, and low compactability are the most significant challenges, requiring more examination. The present paper provides a broad overview of the mentioned challenges, the way they occur, and their adverse influences on the physicomechanical properties of CNT-reinforced metal matrix nanocomposites. The suggested solutions to these issues are fully addressed.

“…The fatigue behavior of magnesium based nanocomposites have also been investigated for AZ31 alloy reinforced with carbon nanotubes (AZ31/CNT) [44] and alumina (AZ31/ Al 2 O 3 ) [45]. The endurance limit of monolithic AZ31 alloy addition was found to be 81 MPa at 10 6 cycles and the addition of 1 vol.% of CNT resulted in an improvement of 40% in the endurance limit to 113 MPa while the addition of 1.5 vol.% of Al 2 O 3 showed an improvement of 36% in the endurance limit to 110 MPa.…”

Magnesium is the lightest structural metal that can be used for engineering applications and its non-toxic nature makes it attractive for use as a biomedical implant. The judicious addition of nanoparticles to magnesium assists in enhancing multiple engineering properties that are critical for its widespread use and are superior to that exhibited by conventional micron-size particles containing composites. The ability to improve mechanical properties with the use of smaller volume fraction of reinforcements while keeping density low makes magnesium nanocomposites an attractive choice for lightweight engineering and bio-resorbable biomedical applications. In view of the exceptional response of magnesium in presence of nano-length scale reinforcements, an attempt is made in this paper to provide a brief review of characteristics of several magnesium nanocomposites illustrating the effects of ceramic and metallic reinforcements to enhance mechanical properties.
