Local chemical fluctuation mediated ductility in body-centered-cubic high-entropy alloys
High-entropy alloys (HEAs) open up a new horizon for discovering un-explored mechanical
properties and deformation mechanisms. Local chemical fluctuations (LCFs) in HEAs were …

Unusual activated processes controlling dislocation motion in body-centered-cubic high-entropy alloys
Atomistic simulations of dislocation mobility reveal that body-centered cubic (BCC) high-
entropy alloys (HEAs) are distinctly different from traditional BCC metals. HEAs are …
