In traditional body-centered cubic (bcc) metals, the core properties of screw dislocations play
a critical role in plastic deformation at low temperatures. Recently, much attention has been …

Understanding the incipient plastic behavior of refractory high-entropy alloys (RHEAs) is
crucial for their high-temperature applications. In this study, the initial dislocation nucleation …

The role of short-range ordering (SRO) in the dislocation kinetics in refractory high-entropy

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

High-entropy and medium-entropy alloys are presumed to have a configurational entropy as
high as that of an ideally mixed solid solution (SS) of multiple elements in near-equal …

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 …

In this work, we perform first-principles calculations, coupled with synchrotron small-angle x-
ray scattering (SAXS) to investigate electronic origins of the chemical short-range ordering …
