High-entropy materials and related complex concentrated materials are considered to be the new ‘avatar’ in physical metallurgy and materials engineering, inspiring novel ideas and approaches to design materials by expanding the compositional space in multi-component and multiprincipal systems. This article is intended to provide critical analyses of the field, summarizing the principlesunderlying the birth and growth of these novel materials, progress over the last 15 years, and expansion of the field from metallic alloys to ceramics. Finally, the challenges ahead and possible way forward are discussed.
