“…In fact, liquid surface energy was high enough to suppress grain growth on the inhibitory effect of HEA. [ 93 ] Farahnaz et al [ 96 ] evaluated the tribological performance of Ti–29Nb–14Ta–4.5Zr (TNTZ) comprising nano‐ in situ second phases fabricated through solution treatment, quenching, and aging process. The strain‐induced formation of second phases (α″, α and ω) was introduced as the dominant mechanism for improved tribological performance.…”

“…In respect of microstructure evolutions, various phenomena such as grain refinement, [93,94] precipitation of hard phases, [22,95] addition or in situ formation of reinforcements, [96,97] and amorphous layer [98] could influence the wear behavior under high-temperature servicing conditions. For instance, adding reinforcement enhances wear resistance at high temperatures by increasing the capability of load bearing and load transferring.…”

Wear property is a main reason for failure, especially for those parts which are mechanically moving and interacting with each other in industrial utilization. High‐entropy alloys (HEAs) are considered promising candidates to possess outstanding tribological factors of performance at high temperatures compared with conventional engineering alloys, which have drawn much attention from academic and industrial points of view. This study is performed to survey the influence of microstructure, grain size, precipitation, reinforcement, and elements addition on the wear resistance of HEAs over a wide temperature range. In this respect, the worn microstructure, wear rate, friction coefficient, hardness, wear track, and subsurface are precisely checked. This review also explores the high‐temperature wear resistance of thermally sprayed and additively manufactured HEAs associated with emphasizing the dominant wear mechanisms through in a wide range of temperatures.

“…Gou et al prepared Ti (C, N) particles reinforced CoCrFeNi HEA via adding NbC to improve its high‐temperature tribological performance. [ 43 ] It was found that both the COF and wear rate of the alloys decreased with the addition of NbC, and the alloy with 3 wt% NbC exhibited the best wear resistance. The excellent tribological performance not only derived from the superior mechanical properties, but also attributed to the existence of stable lubrication tribo‐layer on the worn surface.…”

Wear is an important form of material loss and failure, and it is usually inevitable in almost all mechanical systems with moving parts. The durability and reliability of engineering components are closely related to their wear resistance. Developing advanced materials to alleviate energy and materials losses in moving mechanical systems still remains a great challenge nowadays. The emergence of novel high‐entropy alloys (HEAs) that compose of multiple principal elements holds great promise for the development of materials with extraordinary wear resistance, due to their high hardness, high wear resistance, and excellent corrosion resistance. Herein, the current research progress of the tribology of HEAs under different conditions is reviewed, including high temperature, dry condition, corrosion solution, and oil lubrication. Specifically, the effects of compositions, microstructures, lubricants, and protective oxide layers on the tribological performance of HEAs are summarized. Furthermore, the underlying mechanisms that are responsible for the excellent wear resistance of HEAs under different conditions are discussed. Finally, the current challenges and the future outlooks are emphasized and addressed systematically. In view of the excellent tribological performances and the diversity of compositional design, HEAs have great potential to be applied in a wide range of mechanical systems to minimize wear.

“…Adding TiB 2 into (AlCrFeMnV) 90 Bi 10 resulted in ~95% decrease in wear rate due to the cumulative effect of matrix, reinforcement, refined grains and improved hardness [463]. Gou et al [396] used CoCrFeNi (reinforced with NbC) as a metal binder for Ti (C,N)-based cermet. The hardness and fracture toughness were measured to be 1853 HV and 9.93 MPa•m 1/2 , respectively.…”

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.
