“…It has been researched by many researchers for making composites containing Fe-Al and WC. It was found that the Fe-Al content composites have performed equivalent wear resistance, hardness, and oxidation resistance as WC-Co [43][44][45]. In general, the corrosion resistance of Fe-Al is known to perform better than that of the Co metal [46].…”

Metal matrix composites are mainly used as a cutting tool insert material. These types of materials are essential to maintain desired mechanical and microstructure properties at elevated temperatures due to friction and wear. Nano sized Tungsten Carbide reinforced composites are mostly used for these conditions. The production of sintered nano sized Tungsten Carbide reinforced composites are done by using powder metallurgy. The different mass ratios of elements including mostly Cobalt and the others could be added as binder phase. The binder phase provides to metal matrix composite superior features including high elasticity, good solubility, similar thermal conduction coefficient and, effective liquid phase sintering mechanism. Cobalt is one of the base elements of high-performance superalloys and rechargeable battery technology. Also, 40% of global need supplied by a single country makes itself higher-priced. It is also known that Cobalt is a high skin allergen and carcinogenic. Together with these obstacles, the investigations of low-cost, non-toxic, or reduced-toxicity materials are always needed. In this study, the related current literature has been investigated in detail. The studies focus on an alternative matrix that providing mentioned conditions explained with pros and cons.

“…Cemented carbides are one of the most widely used powder metallurgy products in the manufacture of wear-resistant materials. The reason for this is that these materials have a high correlation between hardness and toughness, compared to other materials such as diamond or high-speed steel [1][2][3]. Cemented carbides usually contain a mixture of hard carbide particles (WC, TiC, TiB 2 , TaC, NbC) with soft and flexible metal bonds such as Co, Fe, and Ni [4][5][6][7].…”

“…The studies to date also show that long-term inhalation exposure to cobalt causes allergic reactions and cancer [5,14]. In addition, the poor corrosion and oxidation resistance of cobalt at temperatures above 600 • C and the poor mechanical properties of cobalt at high temperatures have led researchers to replace this element with other types of binder [2,[4][5][6]13,16]. However, despite the undoubted importance of this subject, no reports have been published to classify the existing work on the oxidation resistance of tungsten carbide cermets and to interpret the data obtained from a statistical point of view.…”

This study presents a conceptual classification scheme to review the literature on improving the oxidation resistance of tungsten carbide by modifying the binder. The first parts of the article are dedicated to the specification of the databases, the search method, and the description of the criteria chosen to classify the articles. Then, the data collected are presented in statistical graphs according to the proposed classification scheme. The data analyzed show that most of the significant improvements in oxidation resistance are achieved with advanced production processes, especially HIP and SPS, which eliminate porosity to a very high degree. In addition, statistical studies showed that the use of new replacement binders, Ni3Al, Fe–based alloys, FeAl, and Al2O3, improved the oxidation properties in 75–100% of cases. Meanwhile, the use of high–entropy alloys (HEAs) as cermet binders may be the subject of future research for oxidation, given the recently published results of good mechanical properties.

“…However, the main drawbacks of iron aluminides are their low ductility and brittle fracture at room temperature and poor wear resistance [4,5]. The addition of ceramic components, such as TiB 2 , TiN, TiC, WC, Al 2 O 3 , and ZrO 2 , as reinforcement has proven to effectively improve the room-temperature mechanical properties in nickel and iron aluminides, their wear resistance and high-temperature strength without degrading the inherent oxidation resistance [11][12][13][14][15].…”

“…A number of manufacturing methods have been applied to produce ceramics-iron aluminide composites, including mechanochemical synthesis [14], spark plasma sintering [15], hot pressing [16], liquid-phase sintering [17], thermal explosion [18] and self-propagating high-temperature synthesis (SHS) [19,20]. Combustion synthesis in the SHS sense is recognized by its high energy effectiveness, rapid reaction process, easy operation, diversity of products, and in situ formation of composite components [21][22][23].…”

Combustion syntheses involving intermetallic and thermitic reactions were conducted to fabricate FeAl–TiB2–Al2O3 composites. Two combustion systems consisting of Fe, Al, Ti, Fe2O3 and B2O3 were studied for formation of xFeAl–yTiB2–Al2O3 composites with x = 1.5–3.5 and y = 0.5–0.8. In the reaction series, thermitic reduction of Fe2O3 and B2O3 by Al thermally activated the reaction between Fe and Al. As a result, the combustion wave of the synthesis reaction was sufficiently exothermic to propagate in a self-sustaining manner. With an increase in TiB2 and FeAl of the composites, the decrease of reaction exothermicity resulted in a decline of the combustion wave velocity and reaction temperature. The activation energy Ea = 88.92 kJ/mol was deduced for the synergetic combustion reaction. Based on XRD analysis, a thorough phase conversion was achieved and composites composed of FeAl, TiB2, and Al2O3 with different contents were obtained. The SEM micrograph showed the FeAl-based composite with a dense and connecting morphology.
