High entropy alloys are receiving significant attention worldwide as a new class of materials that offer unique and attractive properties. However, controversy exists over their nature and the extent to which their structure and properties are derived from the entropy associated with their multi-element chemistries. In this experiment, total scattering will be used to probe the local structure in an fcc high entropy alloy, CrMnFeNiCo, to determine how random the atomic neighbour correlations truly are. If preferential neighbour correlations can be detected, this will challenge the very concept on which this class of materials is based.
