“…Some of the properties exhibited by HEAs include, but are not limited to, excellent high-temperature mechanical properties [23][24][25][26], cryogenic stability [12,[27][28][29], corrosion resistance [30][31][32], and many more. Additionally, the properties can be further modified for superior performance using high-entropy superalloys [33][34][35][36][37], high-entropy steels [38,39], and high-entropy intermetallics [40][41][42], which use similar strengthening strategies as nickel superalloys such as Inconel and Monel [43][44][45][46]. Specific properties can be developed in the design of HEAs such as magnetism [47], hydrogen storage [48], and reinforcing composites [49] With several impressive properties of HEAs, the possible applications are equally numerous.…”

There is little doubt that there is significant potential for high-entropy alloys (HEAs) in cryogenic and aerospace applications. However, given the immense design space for HEAs, there is much more to be explored. This review will focus on four areas of application for HEAs that receive less attention. These focus areas include joining technologies, HEA nanomaterial synthesis, catalysis, and marine applications. The performance of HEAs as a filler metal for welding and brazing as well as their performance as a welded/brazed base metal will be discussed. Various methods for synthesizing HEA nanomaterials are reviewed with specifically highlighted applications in catalysis and energy storage. HEA catalysts, in particular, will be discussed in detail regarding their effectiveness, selectiveness, and stability. Marine applications are explored given the inherent corrosion resistance of HEAs as well as superior antifouling properties that make HEAs an intriguing marine-ready material.

The viability of reinforcing the Al 6061 matrix using AlCrFeNi and AlCrFeNiTi high entropy alloy (HEA) particles is investigated. Body‐centered cubic, A2, and TiC phases are observed in both alloys after 12 h of milling. In situ TiC formation happens during mechanical alloying in AlCrFeNiTi HEA powders. Selected area diffraction patterns are employed in transmission electron investigations to authenticate the presence of distinct phases, affirming their existence within the studied material. Fabricated composites exhibit evenly spaced grains with homogeneous particle dispersion. In comparison to its equivalent, a composite reinforced with AlCrFeNiTi‐C particles exhibits greater grain refinement. Benefiting from dispersion strengthening and grain refinement, both metal matrix composites (MMCs) showcase enhanced attributes. In the case of Al6061/AlCrFeNiTi‐C MMC, a remarkable 25% boost in ultimate tensile strength is achieved, accompanied by a substantial 141.6% improvement in hardness. The findings demonstrate the contribution of HEA particles in improving the characteristics of Al alloys.
