  • High entropy alloysWikipedia

    High-entropy alloys (HEAs) are alloys that are formed by mixing equal or relatively large proportions of (usually) five or more elements.Prior to the synthesis of these substances typical metal alloys comprised one or two major components with smaller amounts of other elements. For example additional elements can be added to iron to improve its properties thereby creating an iron based
