This talk will discuss the challenges of characterizing short-range order (SRO) in Multi-Principal Element Alloys (MPEAs), especially in face-centered cubic (FCC) alloys. A series of results using direct and indirect methods for characterizing SRO in CrCoNi and FeCrCoNi will be presented and compared. The indirect methods include those that measure anomalies in functional properties. The direct methods involve the use of transmission electron microscopy methods including selected area diffraction pattern analysis to assess SRO. A framework will be proposed for establishing correlations between additional intensities and the presence of SRO in MPEAs. Our goal is to provide a better understanding of the ordering tendencies in multi-principal element alloys and highlight the potential of indirect techniques to these ordering tendencies.
