High-entropy materials

In the paper 'Local Nanostructure in Multicomponent High-Entropy Materials' (published in High Entropy Alloys & Materials), Professor Brian Cantor explores the extensive variations, local atomic clusters and associated local lattice strains within multicomponent high-entropy solid-solution single phases.  Samples include fcc Cantor alloys, bcc Senkov alloys and rock-salt-structured Rost mono-oxides.

The paper explains that the number and extent of the variations in the samples increased dramatically to even higher values with an increasing number of components in the material.  It also demonstrates the similar variations in local nanostructure, local atomic clusters and associated local lattice strains surrounding point defects such as vacancies and line defects (dislocations and planar) which influence many important material properties such as diffusion, plastic flow, recrystrallistation, grain growth and catalysis.
