“…In addition to introducing alloy elements and interstitial elements to strengthen the matrix, micro or nanoparticles are added to modify the microstructure and properties of the HEAs. Most of the selected particles are ceramic, such as carbide [102,103,[143][144][145], nitride [67,68,146], and oxide [147,148]. Shen et al [143] have investigated the effect of the addition of SiC to the DEDed CoCrFeNi matrix.…”

“…Therefore, these results demonstrated that the mechanical properties of HEAs can be tailored via carefully adjusting the phase fraction of the strengthener. Jiang et al [147] conducted an investigation to examine the impact of CeO 2 on the microstructure and characteristics of FeCoCrAlNiTi HEAs. They produced coatings of CoCrAlNiTi x (CeO 2 ) (x = 0, 0.5, 1 wt.%) via DED.…”

The advent of high-entropy alloys (HEAs) provides new possibilities for the metallurgical community. CoCrFeNi-based alloys have been widely recognized to demonstrate superior mechanical properties, amongst the high-entropy alloy systems; in particular, they possess an outstanding tensile ductility and work-hardening capacity. Additive manufacturing (AM) uses a layer-by-layer material deposition approach to build parts directly from computer-aided design models, which are capable of producing near-net-shape HEAs with superior mechanical properties, surpassing traditional manufacturing methods that require a time-consuming post-treatment process, such as cutting, milling, and molding. Moreover, the rapid solidification inherent in AM processes induces the formation of high-density dislocations, which are capable of enhancing the mechanical properties of HEAs. This review comprehensively investigates and summarizes the diverse strengthening mechanisms within CoCrFeNi-based alloys produced using AM technologies, with a specific focus on their influence on tensile properties. A correlation is established between the AM processing parameters and the resultant phases and microstructures, as well as the mechanical properties of CoCrFeNi-based HEAs, which provide guidelines to achieve a superior strength–ductility synergy.

“…UTS of these composites was reported to be influenced by the volume fraction of metallic glass [53]. Jiang et al [54] and Chen et al [55] have reported the laser cladding-based fabrication of AlCoCrFeNiTi-CeO2 and AlCoCrFeNiTi-TiC HEAC coatings respectively. Chen et al [55] have added C and B to fabricate self-generated TiC particle reinforced AlCoCrFeNiTi HEAC coating on #45 steel.…”

“…Jiang et al improved the tribological properties of FeCoCrAlNiTi HEA by introducing CeO 2 nanoparticles. [ 98 ] In their study, the microstructure of FeCoCrAlNiTi HEA was remarkably refined with the introduce of the CeO 2 nanoparticles, indicating that the addition of CeO 2 led to the grain boundary strengthening of the refined microstructure. Consequently, the wear resistance of FeCoCrAlNiTi‐ x CeO 2 ( x = 0.5 and 1.0 wt%) coating was significantly enhanced in comparison to FeCoCrAlNiTi HEA.…”

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.
