Abstract

This paper provides general overviews for the recent progress in alloy designs for high-entropy crystalline and glassy alloys in the following aspects. First, the alloy designs for bulk metallic glasses (BMGs) are briefly reviewed by focusing on atomic size differences, mixing enthalpy and valence electron concentration as well, followed by their extension to the other related alloys including high-entropy alloys (HEAs). Then, the historic backgrounds of the high-entropy bulk metallic glasses (HE-BMGs) are dealt with by pointing out the features of the HE-BMGs. Subsequently, the recently-developed HEAs with hcp structure, which are the new ones to the conventional HEAs with bcc, fcc and their mixture structures, are discussed for their future development. Finally, recent alloy designs utilizing crystallographic data acquired from Pettifor map, Pearson's Crystal Data and binary phase diagrams are discussed in order to use them for the development of new alloys in near future.
