“…Tribological studies on HEAs are mostly conducted with variations in content of one element and finding the optimum concentration of the element for minimum wear rate [360,[363][364][365]371,[377][378][379][380]383,384,386,390,394,395,397,398,407,408,412,421,422,424,427,428,431,440,454,455,463,470,472,474]. Furthermore, the effect of Al content on wear properties and hardness has been studied more than any other metal.…”

Alloying has been very common practice in materials engineering to fabricate metals of desirable properties for specific applications. Traditionally, a small amount of the desired material is added to the principal metal. However, a new alloying technique emerged in 2004 with the concept of adding several principal elements in or near equi-atomic concentrations. These are popularly known as high entropy alloys (HEAs) which can have a wide composition range. A vast area of this composition range is still unexplored. The HEAs research community is still trying to identify and characterize the behaviors of these alloys under different scenarios to develop high-performance materials with desired properties and make the next class of advanced materials. Over the years, understanding of the thermodynamics theories, phase stability and manufacturing methods of HEAs has improved. Moreover, HEAs have also shown retention of strength and relevant properties under extreme tribological conditions and radiation. Recent progresses in these fields are surveyed and discussed in this review with a focus on HEAs for use under extreme environments (i.e., wear and irradiation) and their fabrication using additive manufacturing.

“…Adding reinforcement phases in the Al matrix is a common method to address this problem. High hardness reinforcements, such as TiB 2 and SiC, can extremely reduce the wear-rate, thereby improving the performance of the Al matrix composites [4][5][6][7][8][9][10]. For example, the addition of 10 vol% SiC to aluminum decreased the wear-rate by 90%, and the formation of a protective mechanically mixed layer was the main reason for explaining this wear-rate decrease [6].…”

“…For example, the addition of 10 vol% SiC to aluminum decreased the wear-rate by 90%, and the formation of a protective mechanically mixed layer was the main reason for explaining this wear-rate decrease [6]. Some experiments show that TiB 2 addition has been used with success in a striking way with the wear-reducing rate by 95% and increasing the surface hardness of Al alloy from 3.5 GPa to 8.0 GPa [7]. Special reinforcements including graphene nano-platelets and Mg 2 B 2 O 5 whiskers were also investigated by some researchers to improve the wear behavior of aluminum alloys [5,8].…”

The wear of aluminum alloy may be decreased by its reinforcement with quasicrystals (QCs) prepared by melt, which in itself has good wear-resisting properties. This research paper considers the part played by a dense Al-Fe-Cr QC reinforced Al matrix composite fabricated by the directed energy deposition (DED) in reducing wear between sliding surfaces and discusses briefly some of the factors which, in practice, explain ceramic-like properties of quasicrystal including low friction and wear resistance. The hardness of reinforcement phases, QC Al91Fe4Cr5 and Al13(Fe, Cr)4, was up to ∼91 and ∼112 HV respectively, while the Al matrix was just ∼70 HV. Furthermore, the reinforcement phases contributed to form the mechanical mixing layer (MML) which significantly decreased the coefficient of friction (COF) and improves the wear resistance. With the increase of load from 1 N to 5 N, the COF dropped from 0.82 to 0.33 because the higher load was beneficial to the formation of harder and denser MML. Through the comprehensive analysis of the wear test and worn surface, the wear behavior and mechanism of this QC-reinforced Al matrix composite have been explained in detail. The results indicate that the quasicrystal-reinforced Al matrix composites formed by DED are one of the promising wear-resistance materials.

“…Introduction of ceramic particles is an effective way to improve the wear resistance of the alloys [ 14 , 15 , 16 , 17 , 18 , 19 ]. For example, the addition of TiB 2 in the matrix of (AlCrFeMnV) 90 Bi 10 high-entropy alloy reduced the wear rate by 85%, which significantly improved the wear resistance of the material [ 20 ]. TiC is often used as a reinforcing agent due to its high hardness, high melting point, good wettability, and chemical stability [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ].…”

In order to improve the wear resistance of CoCrNi alloy, TiC was introduced into the alloy and wear-resistant CoCrNi/(TiC)x composites were designed. The effects of TiC contents on the microstructure, mechanical properties, and wear resistance of CoCrNi matrix were investigated, respectively. It was found that the TiC produced dissolution and precipitation process in CoCrNi alloy, and a large number of needled and blocky TiC particles were precipitated in the composites. The compressive yield strength of CoCrNi/(TiC)x composites increased with the increasing TiC content. Compared with the CoCrNi alloy, the yield strength of CoCrNi/(TiC)x composites increased from 108 to 1371 MPa, and the corresponding strengthening mechanism contributed to the second phase strengthening. The wear resistance of CoCrNi/(TiC)x composites was also greatly improved due to the strengthening of TiC. Compared with the CoCrNi alloy, the specific wear rate of CoCrNi/(TiC)1.0 alloy was reduced by about 77%. The wear resistance of CoCrNi/(TiC)x composites was enhanced with the increasing content of TiC addition.
