“…In Mg-Al 2 O 3 samples extruded at 350°C after powder milling, a significant damping ability was achieved and attributed to interface character of MMCs [7][8][9][10][11][12][13]. Indeed, CNT/2024 Al composites showed improved damping properties at high temperature as high as 400°C [16][17][18][19].…”

Metal matrix composites (MMCs) possess excellent physical and mechanical properties. The filler reinforcement into the metallic matrix improves the stiffness, specific strength, wear, creep and fatigue properties compared to the conventional engineering materials. The present work is a study of the effect of reinforcement of different types of fillers in metal matrix and their merits and demerits. Effect of different dispersion on the mechanical properties like tensile strength, strain, hardness, wear and fatigue of MMCs and its different applications are also highlighted in the paper. [7][8][9] and borides (TiB2) [8][9][10][11][12][13] have been used as dispersion. As ceramic reinforcements Carborundum, Sic and alumina are widely used in these MMCs. Moreover, different allotropes of carbon like carbon black, fullerenes and carbon nanotubes [15][16][17][18][19][20] have also been investigated by several researchers. CNTs are potential candidates as they confer very high mechanical properties to the metal matrix. They also increase the electrical conductivity, which makes MMCs very attractive materials for electrical applications. Single wall carbon nanotubes (SWCNT) and multi wall carbon nanotubes (MWCNT) both are used as reinforcement in MMCs. Copper-0.1 wt.% MWCNT composites revealed a 47% increase in hardness and bronze-0.1 wt.% SWCNT showed a 20% improved electrical conductivity [18,19]. Intermetallic compounds like (NiAl, Al 3 Ti) have also been dispersed in MMCs [15][16][17][18][19]. AlAl3Ti nanocomposite showed good mechanical properties at high temperature [17][18][19][20], while TiAl-NiAl MMCs revealed high hardness but poor fracture toughness [12,17]. Keywords: Introduction Preparation Methods and Propertiespreparation of MMnCs by conventional casting processes results in an inhomogeneous distribution of particles within the matrix due to low wettability of ceramic nano-particles. For the largescale production of metal matrix nanocomposites, the main problem to face is the low wettability of ceramic nano-particles, which does not allow the preparation of MMCs by conventional casting

“…Ceramic nanoparticles, such as Al 2 O 3 , which have high modulus, hardness, and wear resistance, are reinforcements sometimes added to metal matrices to improve mechanical and tribological properties (Aruri et al, 2013;Baradeswaran and Perumal, 2013;Lu et al, 2013). Graphene has also been considered as a constituent in MMCs due to its favorable mechanical, electrical and thermal properties (Shin et al, 2015).…”

Non-contact methods for characterization of metal matrix composites have the potential to accelerate the development and study of advanced composite materials. In this study, diametrical compression of small disk specimens was used to understand the mechanical properties of metal matrix micro-and nanocomposites. Analysis was performed using an inverse method that couples digital image correlation and the analytical closed-form formulation. This technique was capable of extracting the tension and compression modulus values in the metal matrix nanocomposite (MMNC) disk specimens. Specimens of aluminum and aluminum reinforced with either Al 2 O 3 nanoparticles or graphene nanoplatelets were synthesized using a powder metallurgy approach that involved room temperature milling in ethanol and low temperature drying followed by single action compaction. The elastic and failure properties of MMNC materials prepared using the procedure above are presented.
