“…A number of research groups reported how temperature affected the microstructures and mechanical properties of HEAs in various manufacturing processes [96,[109][110][111][112]. Moreover, the physical or chemical responses of various HEAs under a variety of thermal histories during manufacturing were studied: thermal aging behavior [86,[113][114][115], TaNbHfZrTi synthesis by hydrogenation-dehydrogenation reaction and thermal plasma treatment [116], martensite formation [117][118][119][120], Al x CoCrFeNi formation with high gravity combustion from oxides [121], laser surface melting [122], precipitation behavior [123][124][125][126] and WTaMoNbV synthesis using inductively coupled thermal plasma [127].…”

Alloying has been very common practice in materials engineering to fabricate metals of desirable properties for specific applications. Traditionally, a small amount of the desired material is added to the principal metal. However, a new alloying technique emerged in 2004 with the concept of adding several principal elements in or near equi-atomic concentrations. These are popularly known as high entropy alloys (HEAs) which can have a wide composition range. A vast area of this composition range is still unexplored. The HEAs research community is still trying to identify and characterize the behaviors of these alloys under different scenarios to develop high-performance materials with desired properties and make the next class of advanced materials. Over the years, understanding of the thermodynamics theories, phase stability and manufacturing methods of HEAs has improved. Moreover, HEAs have also shown retention of strength and relevant properties under extreme tribological conditions and radiation. Recent progresses in these fields are surveyed and discussed in this review with a focus on HEAs for use under extreme environments (i.e., wear and irradiation) and their fabrication using additive manufacturing.

“…During the past decade, a series of ferromagnetic HEAs systems such as Fe-Co-Ni-Al-Si, Fe-Co-Ni-Mn-Al, Fe-Co-Ni-Mn-Ga, Fe-Co-Ni-Cr-Si, Fe-Co-Ni-Mn-Si, and Fe-Co-Ni-Cu-Si. have been reported [45][46][47]. As well, non-ferromagnetic elements can significantly influence the magnetic properties of HEAs [36].…”

High-entropy alloys (HEAs) have attracted the attention of scholars due to their outstanding properties such as excellent fracture, and irradiation resistance for various applications. However, the complex composition space hinders the exploration of new HEAs. The traditional experimental trial-and-error method has a long periodicity and is difficult to understand the complexity of the structural characteristics of HEAs. With the rise of the “Materials Genome Initiative”, simulation methods play an important role in accelerating the development of new materials and speeding up the design process of new HEAs. In this chapter, some of the multi-scale simulation methods, such as density functional theory (DFT) calculations and molecular dynamics (MD) methods, used in designing HEAs and predicting their properties are reviewed. The advantages and limitations of these methods are discussed, and the role of computational simulation methods in guiding experiments is illustrated. This study aims to promote the rapid development of computational simulation methods in HEAs.

“…The rapid solidification and cooling rates invariably produce fine microstructures which also enhances the surface properties of the alloys. Chen et al [109] used LSM on HEAs and they mentioned that the surface modification process increased the electrochemical and mechanical properties of the alloys. Ochelik et al [105] found that the solidification rate influences the phases formed using LSM.…”
