 The researchers studied how segregated elements affect the plasticity of nanoscale Co-C-R-C-U-F-A-N-I high entropy alloys, HEAs. They found that segregating certain elements such as copper or nickel can improve the plasticity of the alloys, while segregating chromium can reduce it. This suggests that by controlling the segregation of certain elements, one could engineer HEAs with improved mechanical properties. This article was authored by Arseny M. Kozakov, Azat V.
