“…Fortunately, nowadays, the formation of agglomerations can be minimized either via mechanical alloying (MA) [39] or by mechanical milling process (both dry and wet milling) by adding process control agent (PCA). Certain weight percentage of stearic acid and or other organic compounds (NaCl, Na 2 SO 4 , KCl etc…) with the powders are being added during the ball milling process as PCA [27,40,41]. Very high configurational entropy alloys can be easily produced via HEBM from the mixing of pure elemental powders without forming any intermetallic phases.…”

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.

“…Sintering is a densification process where the powder particles are compacted and formed via applying heat below the melting point or liquefaction point [41] under the inert gas atmosphere. The purpose of this process is to bond all the powders together so the mechanical and physical properties can be improved.…”
