Multi-principal element alloys (MPEAs) are a relatively new class of materials that exhibit promising properties such as high strength, excellent corrosion response, and irradiation resistance. The serrated plastic flow (SPF), which is behavior that is associated with the inhomogeneous deformation in an alloy, can permanently degrade material properties. The current work will give an overview of recent experimental and theoretical results on the SPF phenomenon in MPEAs. In particular, this presentation will highlight the SPF behavior observed in different MPEAs over a wide range of temperatures and strain rates. Analytical methods discussed include the refined composite multiscale entropy analysis and multifractal techniques.
