Experiments and Model for Serration Statistics in Low-Entropy, Medium-Entropy and High-Entropy Alloys [PDF]
Scientific Reports, 2015 AbstractHigh-entropy alloys (HEAs) are new alloys that contain five or more elements in roughly-equal proportion. We present new experiments and theory on the deformation behavior of HEAs under slow stretching (straining) and observe differences, compared to conventional alloys with fewer elements. For a specific range of temperatures and strain-rates,
