In this sense, it is well known that Al composites provide better wear resistance and improved bulk mechanical properties [2]. In particulate metal matrix composites (MMCs), the function of reinforcement particles is to strengthen the metal matrix. The mechanical behavior of the MMCs is greatly influenced by the properties of the matrix and reinforcement, volume fraction, their distribution, and size of reinforcement, as well as the interfacial strength between the matrix and reinforcement [1]. Adequate distribution of the particulate reinforcement in the metal matrix can be attained by the ball milling technique [3; 4; 5; 6; 7; 8]. Aluminum matrix composites have been produced using two methods--liquid state processing (ex-stir casting) and solid-state processing (powder metallurgy, mechanical alloying). In the powder metallurgy processing method, the Al matrix and reinforcement are mixed in order to be compacted with a subsequent sintering process to gain strength. Aluminum MMCs are typically reinforced by oxides or ceramic particles. Considering that in ex situ processing, the reinforcement is added externally to the liquefied metal, problems of wettability and particle agglomeration needed to be resolved [9]. In this regard, the powder metallurgy method emerged with the aim of avoiding wettability and agglomeration problems and promoting a uniform dispersion of reinforcement in the Al matrix. Another strategy to counter the disadvantages of utilizing ex situ processing is to use phases other than ceramics as reinforcements. For example, intermetallic compounds could be considered candidate materials to reinforce Al matrix composites since ordered intermetallic compounds based on the aluminides of transition metals, such as Fe, Ni, Nb, Ti, and Co, have been assessed and studied for their potential application as structural materials at medium and high temperatures [10]. Moreover, the Al contents of these compounds induce the formation of a passive layer of Al oxide, which is responsible for very good corrosion and oxidation resistance at elevated temperatures [11]. Iron aluminides of the type Fe-Al and Fe3 Al exhibit excellent mechanical resistance at high temperatures, low densities, high melting points, and good structural stability; however, efforts were applied to enhance the ductility and impact resistance of these compounds [12]. In terms of producing an MMC with improved mechanical properties along with low density, intermetallic compounds are very suited to these purposes. For example, the intermetallic phases of the Al-Ca binary alloy system are among the materials that can produce very light metal matrix composites, as these phases are extremely low in density [13]. The mechanical resistance of MMCs is significantly influenced by the interfacial strength between the matrix and reinforcement, which depends on the wettability between the metal and reinforcing particles. In this sense, it has been reported that intermetallics can be wetted by molten metal without difficulty. Additionally, they exhibit comparable mechanical behavior and a coefficient of thermal expansion closer to that of Al when compared to hard ceramic phases [14]. Therefore, in recent times, intermetallics based on Ni-Al and Ti-Al systems have been investigated as a new type of reinforcement for MMCs [15; 16; 17; 18]. It is worth noting that the stiffness and wear behavior of the MMCs can be enhanced by the addition of intermetallics. Thus, the purpose of this investigation was to take into account the advantages provided by the powder metallurgy route and the excellent properties that intermetallic compounds possess, in order to fabricate Al matrix composites reinforced with intermetallics of the Fe-Al system. Another goal was to analyze and study the influence of the processing parameters on the microstructure and hardness of the composites in order to achieve desired properties for automotive or aeronautic applications.
