Temperature Effects on Deformation and Serration Behavior of High-Entropy Alloys (HEAs)

JOM, 2014
Many materials are known to deform under shear in an intermittent way with slip avalanches detected as acoustic emission and serrations in the stress–strain curves. Similar serrations have recently been observed in a new class of materials, called high-entropy alloys (HEAs).
