High entropy materials (HEMs) are considered to be a new ‘avatar’ in physical metallurgy and materials engineering. After their seminal discovery in 2004 (refs 1, 2), research activity in HEMs and related materials has been vigorous for the last 13 years. In recent times, HEMs have gained tremendous attention due to their attractive and adjustable properties with a large compositional range and fascinating microstructures. Although the initial discovery was on high entropy alloys (HEAs) consisting of different metals, the research areas have been expanded to different classes of materials such as high entropy refractory alloys, high entropy superalloys, high entropy metallic glass and high entropy ceramics (oxides/nitrides/carbides). Therefore, these are now termed as HEMs.References

High entropy materials (HEMs) as a research field in materials science and engineering has matured over the last few years. In 2004, Yeh et al. and Cantor et al. coined the term ‘high entropy alloys’ (HEAs) for the newly discovered multicomponent and multiprincipal (Co-CrFeNiMn) metallic cocktails; research activities were mainly centred on the metallic alloys. This has led to the discovery of many FCC and BCC HEAs, including refractory HEAs.References
