“…Several challenges must be overcome in order to enhance the engineering usage of MMCs. Compared to the conventional aluminum alloys, particle reinforced aluminum matrix composites (Al-MMCp) possess high-specific elastic modulus and strength, light weight, good wear resistance and excellent properties at elevated temperature [1][2][3]. Because of these excellent mechanical properties, particle reinforced aluminum matrix composites have been widely used in aerospace and infrastructure industries.…”

The scope of the research work is the production and characterization of Al matrix composites reinforced with WC ceramic nanoparticles. The synthesis process was powder metallurgy. The produced composites were examined as far as their microstructure and mechanical properties (resistance to wear, micro/macrohardness). Intermetallic phases (Al 12 W and Al 2 Cu) were identified in the microstrucutre. Al 4 C 3 was not detected in the composites. Adding more than 5 wt% WC to the aluminum, microhardness and wear resistance exceed the values of Al alloy. Composites having weak interface bond performed the highest wear rate.

“…According to the previous studies, 4) the matrix was prepared through mechanical alloying using a high energy attritor ball mill to produce the nanostructure matrix powder of the composites. 4) Different concentrations of nanostructured (submicron size) pre alloyed ¢-Al 3 Mg 2 intermetallic compound, as reinforcement were added to the matrix to improve the hardness and wear resistance of the MMCs. Proper distribution of the reinforcing particles in the matrix is very important in blending process, 12) then the effect of different weight fractions of reinforcement on the wear resistance and hardness of a new generation nanocrystalline matrix composites are investigated.…”

“…2) Mechanical alloying has been successfully used for the preparation of supersaturated solid solutions in the AlCu system. 3,4) According to binary phase diagram of AlCu ( Fig. 1(a)), the equilibrium solid solubility of Cu in Al at room temperature is about 0 at% and the equilibrium solid solubility of Mg in Al at room temperature is only about 1 at%.…”

“…5) For MA of AlCu alloys, depending on the initial solute content in the elemental powder mixture, the milling parameters and the presence of processing control agents, 3,6) the solid solubility of Cu in Al can be extended far beyond the equilibrium concentrations up to 4.5 mass% Cu at room temperature as it is studied in previous investigations. 4) The pre-alloyed AlMg powders are first metastable fcc structure solid solutions and then during melting and subsequent heating, transform into the stable phases (¢-Al 3 Mg 2 and/or £-Al 12 Mg 17 ). 7,8) In this work, both mechanical alloying (MA) and mechanical milling (MM) techniques have been used to produce supersaturated Al(Cu) solid solutions with Cu content of 4.5 mass% in order to achieve the heat treatable composite matrix and mechanical milling (MM) was applied to reduce particle size of pre-alloyed intermetallic compound of Al 3 Mg 2 down to nanometer scale.…”

AlMg alloys close to ¢-Al 3 Mg 2 intermetallic phase were processed by neutral gas coverage melting process of pure elemental Al and Mg with the composition of Al40 mass% Mg. Mechanical milling was applied in order to convert the pre-alloyed ingots to nanocrystalline or amorphous alloy. X-ray diffraction and transmission electron microscopy (TEM) tests were carried out to investigate the formation of Al 3 Mg 2 single phase nanoparticle. Having prepared the single phase intermetallic, it was added to the pre-alloyed matrix powder of Al4.5 mass% Cu, in different contents. The effect of the reinforcing agent on the microhardness and wear behavior of the nanocopmosites were studied thoroughly with the aid of press-sinter methodology and quantitative data recorders via pin-on-disk wear test. The results of microhardness tests revealed that the hardness of nanocomposites is significantly improved with increasing reinforcement content with in the matrix. The coexisted wear mechanisms, mainly delamination and abrasive, of the consolidated nanocopmosites were investigated through scanning electron microscopy (SEM) and TEM observations.

Metal matrix nanocomposites (MMNCs) are an emerging class of metals with nanosized reinforcements and have been investigated extensively in recent decades due to their promising properties for widespread applications such as aerospace, automotive, biomedical, and electronics. In this article, a comprehensive review is presented on the science and engineering aspects of MMNCs, especially the processing, microstructures, and properties of MMNCs. Common processing and manufacturing approaches and post‐processing of MMNCs are discussed. Recent advances in the unusual mechanical, physical, and chemical properties of MMNCs are reviewed. Furthermore, the latest progress on the fundamental study of interactions between nanoparticles and metals, including dispersion, pushing, and engulfment during solidification, nucleation, and phase control, is presented. It is worth noting that the exciting opportunities of nanotechnology‐enabled metallurgy (nanotech metallurgy), which have grown out of the domain of MMNCs recently, are also presented briefly.
