“…Whereas popular solid state methods are conventional powder metallurgy (PM), high-energy ball milling/mechanical alloying (MA), diffusion bonding, friction stir processing (FSP), and so on. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] Matrix and reinforcements are carefully selected based on criteria like density, elastic modulus, hardness, thermal stability, and CTE. Compatibility with matrix (wettability, reaction with matrix), size, morphology, availability, and cost are other deciding factors for making composites of desired properties.…”

Aluminum (Al)-based composites are on increasing usage in sectors like ground transportation, aerospace, sports, and infrastructure because of the improved properties such as high strength to weight ratio, corrosion, fatigue, and wear resistance. Several applications involving dynamic contact stresses require excellent wear and frictional performance for improved life. Nanocomposites are found to perform exceedingly better than microcomposites and alloys in several lab scale tribological investigations carried out so far in the last decade. In this article, an attempt is made to review those published reports about dry sliding tribological behavior of particulate-reinforced Al nanocomposites. Wear and friction being system properties are found to get influenced by intrinsic factors such as reinforcement, fabrication method, microstructure; extrinsic parameters like load, speed, contact conditions and the system generated in situ tribolayer all being interrelated.

“…The combination of strength enhancement of the MMNC material with the beneficial processing of SSC was reported by DeCicco et al [39,41] with reduced shrinkage, progressive mold filling and increased ductility for the semi-solid cast zinc alloy AC43A with 0.5 wt% SiC β (20-30 nm) nanoparticle addition compared to liquid cast monolithic AC43A zinc alloy and liquid cast AC43A/SiC nanocomposite, as shown in Figure 5. The observed strength increase in the liquid cast AC43A/SiC systems is relatively small compared to other nanocomposite systems.…”

Lightweight high-strength metal matrix nano-composites (MMNCs) can be used in a wide variety of applications, e.g., aerospace, automotive, and biomedical engineering, owing to their sustainability, increased specific strength/stiffness, enhanced elevated temperature strength, improved wear, or corrosion resistance. A metallic matrix, commonly comprising of light aluminum or magnesium alloys, can be significantly strengthened even by very low weight fractions (~1 wt%) of well-dispersed nanoparticles. This review discusses the recent advancements in the fabrication of metal matrix nanocomposites starting with manufacturing routes and different nanoparticles, intricacies of the underlying physics, and the mechanisms of particle dispersion in a particle-metal composite system. Thereafter, the microstructural influences of the nanoparticles on the composite system are outlined and the theory of the strengthening mechanisms is also explained. Finally, microstructural, mechanical, and tribological properties of the selected MMNCs are discussed as well.
