“…Scientists have found that the incorporation of different types of reinforcement materials, such as ceramics, metals, and intermetallic particles, have proved to be an effective way to increase the wear properties of the aluminum matrix. This is how AMC's have been manufactured with the addition of different compounds that are intended to be the reinforcers of the metallic matrix, thus the AMC's have been manufactured with SiC/B 4 C [7], SiC/Al 2 O 3 [8], TiC [9], alloys of Fe-Cr-Al/Y 2 O 3 [10], FeC/Cr 2 C [11]. Likewise, they have been processed through very different methods, such as stir casting [12], powder metallurgy [13], spray atomization and co-deposition [14], plasma spraying [15], and squeeze-casting [16].…”

“…These composites have been manufactured to produce lightweight components with high, specific mechanical properties such as wear resistance, thus they have been applied in the automotive and aeronautical industry where the reduction of weight, wear, friction, and low coefficient of thermal expansion are important [1]. A situation to consider is that, to date, the production of the AMC's has been conducted through very sophisticated methods, using a special aluminum alloy [8,10,11] or using very special reinforcing materials, such as graphene [17][18][19]. Depending on the route of processing and according to the findings in the literature, the incorporation of non-metallic ceramic reinforcements in aluminum increase the mechanical properties of AMC's, resulting advantages such as: hardness, strength, fatigue, fracture, degradation, and corrosion resistance, due to the small grain size and homogeneity of their microstructures [20].…”

Aluminum matrix composites have recently taken an important role in advanced applications because they have a good combination of physical and chemical properties. For this reason, in this work, aluminum composites, with additions of ceramic particles (mullite or tungsten carbide), were manufactured in order to determine the effect of those particles on the mechanical properties and microstructure of aluminum. The manufacture of the composites was carried out by means of powder metallurgy. We studied composites with additions of 0.5 and 1 vol.% of the respective ceramic. Composites were sintered at 580 and 601 °C, which corresponds to 88 and 91% of the melting point of aluminum, respectively. Observations in SEM, together with EDX analysis, confirm that mullite particles are located at intragranular and transgranular positions of the aluminum matrix, while tungsten carbide particles were found mostly at intragranular areas of the matrix. From the analysis of the studied ceramics, it was found that with the use of mullite, there are greater improvements in the hardness and elastic modulus of the manufactured composite.

“…In addition to factors related to raw materials, operational factors also affect its composition, such as the type of furnace, operating cycle, and gas cleaning system efficiency 14 . Powder Metallurgy (PM) is an appropriate method for metal matrix composite processing due to its simple processing and ample applications in different fields, such as transportation, the aerospace and infrastructure 15,16 . PM allows for recycling of solid waste in its solid state, transforming it into useful products through the reduction of metal oxides present in the steelmaking dusts and in its composition during sintering 17 .…”

Study on Effect of EAFD Particulate Reinforcement in AA7075 Aluminum Matrix Composites

et al. 2018

Eletric arc furnace dust is dangerous solid waste that is generated in steel manufacturing processes. The utilization of the dust from these industries avoids disposing it into industrial waste landfills and saves costs. In this study, an attempt has been made to fabricate aluminum matrix composites reinforced with EAFD particulate, throught the conventional powder metallurgy technique. Al-5%EAFD proposed was then compared to the AA7075 alloy, manufactured under the same conditions. According to the results obtained, the addition of EAFD into aluminum matrix resulted in increased microhardness values and had significant contributuion to improve Storage modulus compared with the base metal. The reinforcement particle was uniformly dispersed into the matrix and intermetallic phases were not observed in the content of waste blended into the composite.

Nonoxide ceramics excel among the reinforcements used for aluminum matrix composites due to their variety of morphologies and mechanical properties. Among these reinforcements are carbides (SiC, B4C, and WC); carbon materials (graphite, carbon fibers, carbon nanotubes, and graphene); nitrides (silicon nitride [Si3N4] and BN); and hollow Fe spheres. Although the effect of adding different percentages of reinforcements has been widely studied for Al matrices, matrix–reinforcement interactions need more attention. The consequences of these interactions can include interface formation, loss of alloying elements, reinforcement deterioration, modifications in the matrix microstructure, different precipitation sequences and kinetics, and interfacial diffusion of elements. These interactions may be significantly modified by the alloying elements, needing more in-depth analyses for a correct selection of the matrix–reinforcement system. Al matrices with Si, Cu, and Mg outstand, and the focus of the present work is their reciprocal interactions with nonoxide reinforcements. The novelty of this review consists of the analysis and discussion of these interactions, emphasizing the modifications originated by each one of these alloying elements, and the conditions needed to increase or avoid their effects on the composite. Besides, an analysis of the crystallography of the generated interfaces is presented, including their impact on mechanical properties. This could be helpful for a better understanding and selection of the matrix–reinforcement system, also serving as a benchmark study.
