“…[122][123][124] Non-metallic elements such as C, B, and N can also be incorporated to achieve even higher strength. [14,99,100,125,126] Additionally, HEAs can also be prepared by other process and/or in other forms. For example, HEAs can be processed by a wrought process including homogenization, hot/cold working, and annealing [62,64] to eliminate casting defects and improve microstructure.…”

High-entropy alloys (HEAs) are alloys with five or more principal elements. Due to the distinct design concept, these alloys often exhibit unusual properties. Thus, there has been significant interest in these materials, leading to an emerging yet exciting new field. This paper briefly reviews some critical aspects of HEAs, including core effects, phases and crystal structures, mechanical properties, high-temperature properties, structural stabilities, and corrosion behaviors. Current challenges and important future directions are also pointed out.

High-entropy alloy layer up to 150 lm in thickness was formed on H13 substrate with a metallurgical bonding at the coating/substrate interface. Simple solid solution phases were formed in the coating layer with a typical microstructure composed of both dendrite and interdendrite. The microstructure at the top of the cladding zone consists of equiaxed grains while that at the bottom consists of columnar grains. The coating layer exhibits great enhancement in microhardness and wear resistance compared with the H13 substrate.

“…Researchers usually either replace one of the elements with a different element, or simply add other element into the classic systems. For example, derivative systems alloyed with Mo, Mn, Si, B, Zr, Ni, Nb, V, Y, Sn, Zn, C [29][30][31][32][33][34][35][36][37][38] have been reported. These early results provided important understanding of the composition-phase-property relationship in HEAs, which made composition design and phase control possible to certain extent.…”

High-entropy alloys (HEAs) have recently become a vibrant field of study in the metallic materials area. In the early years, the design of HEAs was more of an exploratory nature. The selection of compositions was somewhat arbitrary, and there was typically no specific goal to be achieved in the design. Very recently, however, the development of HEAs has gradually entered a different stage. Unlike the early alloys, HEAs developed nowadays are usually designed to meet clear goals, and have carefully chosen components, deliberately introduced multiple phases, and tailored microstructures. These alloys are referred to as advanced HEAs. In this paper, the progress in advanced HEAs is briefly reviewed. The design strategies for these materials are examined and are classified into three categories. Representative works in each category are presented. Finally, important issues and future directions in the development of advanced HEAs are pointed out and discussed.
