Theoretical antiferromagnetism of ordered face-centered cubic Cr-Ni alloys
Flynn Walsh, Robert O. Ritchie, Mark Asta
Contrary to prior calculations, the Ni-rich ordered structures of the Cr-Ni alloy system are found to be antiferromagnetic under semi-local density-functional theory. The optimizat…
Extra electron reflections in concentrated alloys do not necessitate short-range order
Flynn Walsh, Mingwei Zhang, Robert O. Ritchie +2
In many concentrated alloys of current interest, the observation of diffuse superlattice intensities by transmission electron microscopy has been attributed to chemical short-range…
Exceptional fracture toughness of CrCoNi-based medium- and high-entropy alloys close to liquid helium temperatures
Dong Liu, Qin Yu, Saurabh Kabra +10
Medium- and high-entropy alloys based on the CrCoNi-system have been shown to display outstanding strength, tensile ductility and fracture toughness (damage-tolerance properties),…
One Dimensional Wormhole Corrosion in Metals
Yang Yang, Weiyue Zhou, Sheng Yin +16
Corrosion is a ubiquitous failure mode of materials in extreme environments. The more localized it is, the more difficult it is to detect and more deleterious its effects. Often, t…
Magnetically driven short-range order can explain anomalous measurements in CrCoNi
Flynn Walsh, Mark Asta, Robert O. Ritchie
The presence, nature, and impact of chemical short-range order in the multi-principal element alloy CrCoNi are all topics of current interest and debate. First-principles calculati…
Ab initio modeling of the energy landscape for screw dislocations in body-centered cubic high-entropy alloys
Sheng Yin, Jun Ding, Mark Asta +1
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…
