“…Since the appearance of PM HEAs, many works were performed to try to analyse the feasibility of these materials as a binder, especially since 2014 ( [47,150,243]) and 2015 [48]. Over the last few months, there has been a dramatic increase in papers dealing with this topic ( [62,129,159,167]).…”

High-entropy alloys (HEAs) have attracted a great deal of interest over the last 14 years. One reason for this level of interest is related to these alloys breaking the alloying principles that have been applied for many centuries. Thus, HEAs usually possess a single phase (contrary to expectations according to the composition of the alloy) and exhibit a high level of performance in different properties related to many developing areas in industry. Despite this significant interest, most HEAs have been developed via ingot metallurgy. More recently, powder metallurgy (PM) has appeared as an interesting alternative for further developing this family of alloys to possibly widen the field of nanostructures in HEAs and improve some capabilities of these alloys. In this paper, PM methods applied to HEAs are reviewed, and some possible ways to develop the use of powders as raw materials are introduced.

“…A refractory high-entropy alloy of HfNbTiVSi 0.5 was synthesized by Zhang et al [29], the alloys were composed by BCC solid solution and a multi-component silicide ((Hf, Nb, Ti)-Si), the research results indicate that the generate of silicide is beneficial for the room temperature strength, ductility and the elevated temperature properties. Lin et al [30] found that the addition of TiC in Co 1.5 CrFeNi 1.5 Ti 0.5 HEAs can improve the hardness-toughness combination of the alloys. Wang et al [31] investigated the anti-penetration performance of high entropy alloy, the results indicated that more uneven the ceramic distribution, the better the anti-penetration performance.…”

To enhance the strength of single FCC phase high entropy alloys, TiC was selected as reinforced phase to improve the properties of high entropy alloys (HEAs). Therefore, a series of TiC/Al 0.6 CrFe 2 Ni 2 high entropy alloys with different TiC content which ranging from 0 to 5 vol% were prepared by vacuum arc melting furnace. The phase compositions, microstructures and mechanical properties of alloys were investigated detailedly. The results show that TiC has no effect on phase composition of the alloys, but the addition of ceramic phase TiC has an advantageous effect on the mechanical properties of alloys, the yield strength of TiC/Al 0.6 CrFe 2 Ni 2 HEAs increases due to the refined of grain size, when TiC content is 2.50 vol%, alloy has better properties, the yield strength and Vickers hardness are 576.93 MPa and 244 HV, respectively.

Available online xxxxCermets based on Ti(C,N) have interesting properties, such as high wear resistance, high chemical stability and good mechanical strength at high temperature, but to become a viable alternative to cemented carbides, the fracture toughness and damage tolerance must be significantly improved. Complete solid-solution cermets (CSCs) have been proposed to further improve the mechanical properties of these materials. However, to develop this family of cermets with a high level of quality and reliability, using pre-fabricated complex carbonitrides is necessary instead of unalloyed mixtures as the raw ceramic material. A mechanochemical process called mechanically induced self-sustaining reaction (MSR) is suitable to obtain these complex carbonitrides with high stoichiometric control. On the other hand, high entropy alloys (HEAs), which can also be obtained by mechanochemical processes, are a good candidate to replace the current binder phase in cermets because they exhibit high strength and ductility at high temperature and good resistance to both wear and corrosion. In this work, a new family of CSCs based on (Ti,Ta,Nb)C x N 1−x with HEAs belonging to the Fe-Co-Ni-Cr-Mn-V system as the binder phase is developed by mechanochemical processes. With only two constituent phases, these cermets have a simple microstructure but a high compositional complexity because both the ceramic and binder phases are complex solid solutions with at least five components.
