“…In summary, the HPT method can be considered not only a processing route for HEAs [51][52][53][54][55][56][57][58][59][60][61][62][63] but also a fast synthesis route to produce various kinds of high-entropy materials, including metallic alloys with high hardness [63], hydrides for hydrogen storage [75], oxides for photocatalytic hydrogen production [76] and oxynitrides with large light absorbance [77]. Compared to conventional synthesis routes for metallic [43,44,[47][48][49][50] and non-metallic [65][66][67][68][69][70][71][72][73][74] HEAs, the HPT method provides a fast laboratory-scale route that is applicable to almost any kind of materials [21][22][23][24][25][26][27][28].…”

“…Although HEAs have generally high strength [47][48][49][50], it was shown that their strength can be further enhanced by SPD processing. For example, the HPT method was successfully used for the hardening of several HEAs, such as CoCrFeMnNi [51,52], Al 0.3 CoCrFeNi [53,54], Al 0.5 CoCrFeMnNi [55], AlCrFeCoNiNb [56], TiZrNbHfTa [57], CrFe 2 NiMnV0.25 [58], CoCrFeNi [59], TiZrCrMn-FeNi [60], TiAlFeCoNi [61], TiAlFeCoNi-C [62] and CoCrFeMnNi-C [63]. More recently, the HPT method was used to impart ultra-SPD and synthesize CoCrFeMnNi with high hardness [64].…”

High-pressure torsion (HPT) is widely used not only as a severe plastic deformation (SPD) method to produce ultrafine-grained metals but also as a mechanical alloying technique to synthesize different alloys. In recent years, there have been several attempts to synthesize functional high-entropy alloys using the HPT method. In this paper, the application of HPT to synthesize high-entropy materials including metallic alloys, hydrides, oxides and oxynitrides for enhanced mechanical and hydrogen storage properties, photocatalytic hydrogen production and high light absorbance is reviewed.

“…Nagase et al (2020) found that Ti-Zr-Hf-Cr-Mo and Ti-Zr-Hf-Co-Cr-Mo HEAs showed excellent biocompatibility compared with CP-Ti. Edalati et al (2020) have studied TiAlFeCoNi HEA exhibited ultra-high hardness and favorable cellular activity by a combination of MTT assay and microhardness measurements. Todai et al designed a new TiNbTaZrMo HAE that shows good biocompatibility compares to Cp-Ti.…”

With the continuous progress and development in the biomedicine field, metallic biomedical materials have attracted the considerable attention of researchers, but the related procedures need to be further developed. Since the traditional metal implant materials are not highly compatible with the human body, the modern materials with excellent mechanical properties and proper biocompatibility should be developed urgently in order to solve any adverse reactions caused by the long-term implantations. The advent of the high-entropy alloy (HEA) as an innovative and advanced idea emerged to develop the medical implant materials through the specific HEA designs. The properties of these HEA materials can be predicted and regulated. In this paper, the progression and application of titanium-based HEAs, as well as their preparation and biological evaluation methods, are comprehensively reviewed. Additionally, the prospects for the development and use of these alloys in implant applications are put forward.

“…In the biocompatible HEAs, some experts use the empirical data and thermodynamic calculations to design HEAs, such as TiAlFeCoNi, TiZrHfCrMo, and TiZrHfCoCrMo. [ 240–243 ] The biocompatible HEAs have better cellular metabolic activity and hardness than Ti alloys and Ti6Al7Nb alloys. These studies have made some important achievements in improving the biocompatibility and hardness of materials, and laid a foundation for the preparation technology of biocompatible HEAs.…”

The performances of high‐entropy materials (HEMs), including high‐entropy alloys, high‐entropy ceramics, and high‐entropy polymers, with unique characteristics (high mixing entropy, serious lattice distortion, and short‐range order) determined by experiments are out of the ordinary, such as the excellent mechanical properties. The important research methods on HEMs are briefly introduced from the physical modeling, multiscale simulation, and experiments at various scales. The microstructures (dislocation, twinning, grain boundary, and phase) and performances (mechanical property, physical property, chemical property, optical property, medical property, and irradiation property) are summarized. Future directions of research and development with a focus on modeling and simulation in HEMs are discussed. In the next, HEMs with the unique properties would be promising candidates for industrial applications beyond conventional alloys.
