Abstract
Body-centered-cubic (BCC) high-entropy alloys (HEAs) composed of elements in the Ti–V–Cr–Zr–Mo–Nb–Hf–Ta–W family at near equal concentrations and the different atom types occupying the crystalline BCC lattice sites at random. These materials exhibit outstanding mechanical and physical properties at elevated temperatures, making them promising candidates for elevated-temperature applications. In this chapter, the principles for alloy design of BCC HEAs with good mechanical properties and superior wear, corrosion, and irradiation resistance are critically discussed. The microstructures, including the short-range order and intermediate and complex phases, are presented, and the mechanical properties at cryogenic, ambient, and elevated temperatures are systematically assessed. This chapter can serve as a guide for the development of advanced BCC HEAs for structural and functional applications.
