“…The alloys prepared from the liquid phase usually have many structural defects such as voids, porosity, and a generally low ascast hardness [4]. Recently, further developments in the powder metallurgy route provided promising results [25,28] despite a higher pore density for samples produced by mechanical alloying (MA) followed by consolidation [29]. However, the solidification from the molten state is usually accompanied by microsegregations, while by the MA process, more homogenous chemical distribution and solid solubility extension could be reached [15].…”

“…Arc melting is currently one of the most commonly used preparation methods for the production of bulk HEAs ( Baldenebro-Lopez et al, 2015 ; Chen Y. et al, 2018 ; Hou et al, 2019 ; Zhang J. et al, 2020 ). The process involves pouring a certain proportion of metallic materials into the tongs.…”

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.

“…Though it is a relatively expensive process, this technique can give improved mechanical properties. For comparison between AM and MA technique as an example, Baldenebro-Lopez et al [49] fabricated AlCoFeMoNiTi HEA by MA with BPR of 1:5 for 10 h under argon atmosphere. The HEA powders were pressed in a die with a compaction pressure of 1.5 GPa (green samples); then sintered at 1423 K under Ar atmosphere for 3 h. In parallel, some of the same green samples were melted in the AM process under Ar atmosphere (re-melted five times to have homogenous melt).…”

High entropy alloys (HEAs) are being attracted recently by several researchers, scientists, and academicians to achieve extraordinary and outstanding properties that cannot be obtained from conventional alloys. HEAs are multicomponent alloys in which a minimum of five metallic elements are mixed in an equal molar or non-equal molar ratio. The rapid growth of this field produces a huge amount of scientific papers over the last decade. However, still, there is a need to review various manufacturing methods and their results. Also, the outcome of the scientific articles related to HEAs has ignored the various methods of synthesizing and manufacturing. In this review article, an attempt was made and largely concentrated on the methods and techniques that can be used in the manufacturing and synthesizing of the HEAs. Recently, the properties of HEAs become much better when compared to conventional alloys. Some techniques have succeeded in producing ultrafine microstructure grains which become a leap in industrial fields. Now, the manufacturing methods of conventional alloys are almost familiar and implemented according to the suggestions given by the researchers and academicians based on their work. Therefore, the present review article has demonstrated various methods of manufacturing of HEAs with novel schematics with a preview description for more understanding of the basic work criteria. Besides, this article has reviewed the outcomes of several research articles related to several methods, then compared the outcome of each method with the corresponding mechanical properties, and major challenges of HEAs are discussed and reported.
