Solute misfit and solute interaction effects on strengthening: A case study in AuNi

William Curtin, Shankha Nag, Binglun Yin

AuNi is a classic long-studied fcc alloy combining a very "large"atom (Au) and a very "small"atom (Ni), and the large atomic size misfits suggest very high strengthening. Here, AuNi is used as a model alloy for the testing of new strengthening theories in ...

Constraining the baryonic feedback with cosmic shear using the DES Year-3 small-scale measurements

Eduardo Sanchez, Binglun Yin, Yi Zhang, Jonathan Andrew Blazek

We use the small scales of the Dark Energy Survey (DES) Year-3 cosmic shear measurements, which are excluded from the DES Year-3 cosmological analysis, to constrain the baryonic feedback. To model the baryonic feedback, we adopt a baryonic correction model ...

A ductility criterion for bcc high entropy alloys

William Curtin, Binglun Yin, Eleanor Yi Kei Mak

A current goal driving alloy development is the identification of alloy compositions for high temperature applications but with the additional requirement of sufficient ductility at ambient temperatures. Multicomponent, single-phase, polycrystalline High E ...

Machine learning for metallurgy II. A neural-network potential for magnesium

William Curtin, Binglun Yin, Eleanor Yi Kei Mak

Interatomic potentials are essential for studying fundamental mechanisms of deformation and failure in metals and alloys because the relevant defects (dislocations, cracks, etc.) are far above the scales accessible to first-principles studies. Existing pot ...

Design of Ductile Rare-Earth-Free Magnesium Alloys

William Curtin, Zhaoxuan Wu, Binglun Yin, Rasool Ahmad

Pure Mg has low ductility due to a transition of < c+a > pyramidal dislocations to a sessile basal-oriented structure. Dilute alloying generally improves ductility. Enhancement of pyramidal cross-slip from the lower-energy pyramidal II plane to the higher- ...

Origin of high strength in the CoCrFeNiPd high-entropy alloy

William Curtin, Binglun Yin

IMPACT STATEMENT Experiments and theory are highlighting chemical ordering in high-entropy alloys (HEAs) as important for mechanical properties but the high strength in CoCrFeNiPd is predicted here to be achievable in the random alloy due to the large misf ...

Yield strength and misfit volumes of NiCoCr and implications for short-range-order

William Curtin, Binglun Yin

The face-centered cubic medium-entropy alloy NiCoCr has received considerable attention for its good mechanical properties, uncertain stacking fault energy, etc, some of which have been attributed to chemical short-range order (SRO). Here, we examine the y ...

Vanadium is an optimal element for strengthening in both fcc and bcc high-entropy alloys

William Curtin, Francesco Maresca, Binglun Yin

The element Vanadium (V) appears unique among alloying elements for providing high strengthening in both the fcc Co-Cr-Fe-Mn-Ni-V and bcc Cr-Mo-Nb-Ta-V-W-Hf-Ti-Zr high-entropy alloy families. The origin of Vanadium's special role is its atomic volume: larg ...

Designing high ductility in magnesium alloys

William Curtin, Zhaoxuan Wu, Binglun Yin, Rasool Ahmad

The thermally activated pyramidal-to-basal (PB) transition of (c + a) dislocations, transforming glissile pyramidal dissociated core structures into sessile basal dissociated ones, lies at the origin of low ductility in pure magnesium (Mg). Solute-accelera ...

First-principles-based prediction of yield strength in the RhIrPdPtNiCu high-entropy alloy

William Curtin, Binglun Yin

High-entropy alloys are random alloys with five or more components, often near equi-composition, that often exhibit excellent mechanical properties. Guiding the design of new materials across the wide composition space requires an ability to compute necess ...

Softening and hardening of yield stress by hydrogen–solute interactions

William Curtin, Ali Tehranchi, Binglun Yin

Hydrogen atoms have a wide variety of effects on the mechanical performance of metals, and the underlying mechanisms associated with effects on plastic flow and embrittlement remain to be discovered or validated. Here, the reduction in the plastic flow str ...

First-principles calculations of stacking fault energies in Mg-Y, Mg-Al and Mg-Zn alloys and implications for < c plus a > activity

William Curtin, Zhaoxuan Wu, Binglun Yin

Mg-3wt.%RE alloys show substantially enhanced < c + a > activity as compared to pure Mg or other Mg-Al, Mg-Zn alloys of similar grain sizes. Activation of < c + a > slip has been postulated to be associated with the reduction of the basal Li stacking fault ...

Comprehensive first-principles study of stable stacking faults in hcp metals

William Curtin, Zhaoxuan Wu, Binglun Yin

The plastic deformation in hcp metals is complex, with the associated dislocation core structures and properties not well understood on many slip planes in most hcp metals. A first step in establishing the dislocation properties is to examine the stable st ...

Energetics of dislocation transformations in hcp metals

William Curtin, Zhaoxuan Wu, Binglun Yin

Dislocation core structures of hcp metals are highly complex and differ significantly among the hcp family. Some dislocations undergo unconventional transformations that have significant effects on the material plastic flow. Here, the energetics of disloca ...
