Low‑temperature method enables custom high‑entropy alloys

Berkeley Lab made high‑entropy alloys at 25–80 °C with water‑based chloride salts and liquid gallium, scaling the reaction to produce several grams in seconds. Read more: getnews.me/low-temperature-method-e... #highentropyalloys #materials

It was really great to speak in the webinar series for the MuST Program for Disordered Materials today, talking about some of the work we have been doing recently on #HighEntropyAlloys 🔩

Competition between phase ordering and phase segregation in the TixNbMoTaW and TixVNbMoTaW refractory high-entropy alloys Refractory high-entropy alloys are under consideration for applications where materials are subjected to high temperatures and levels of radiation, such as in t

Back on the theme of #HighEntropyAlloys, this work from early 2024 examined how the addition of Ti to refractory high-entropy alloys led to predicted #Multiphase behaviour:

We studied how the addition of Ti affected the Nb-Mo-Ta-W and V-Nb-Mo-Ta-W #Alloys

Interplay between magnetism and short-range order in medium- and high-entropy alloys: CrCoNi, CrFeCoNi, and CrMnFeCoNi The impact of magnetism on predicted atomic short-range order in three medium- and high-entropy alloys is studied using a first-principles all-electron Landau-type linear-response theory, coupled with...

In 2023, we published another article working on #HighEntropyAlloys in Physical Review Materials:

doi.org/10.1103/Phys...

Here, we showed how the simulated magnetic state of the alloys alters the #FreeEnergy landscape, changing the predicted #PhaseEquilibria for CrCoNi, CrFeCoNi, and CrMnFeCoNi

Short-range order and compositional phase stability in refractory high-entropy alloys via first-principles theory and atomistic modeling: NbMoTa, NbMoTaW, and VNbMoTaW Using an all-electron, first-principles, Landau-type theory, we study the nature of short-range order and compositional phase stability in equiatomic refractory high-entropy alloys, NbMoTa, NbMoTaW, a...

Now, my third journal article, this time published in Physical Review Materials in 2023:

doi.org/10.1103/Phys...

Taking the computational approach developed in our earlier work, this time we examined the phase stability of the #Refractory #HighEntropyAlloys, examining atomic ordering tendencies

Compositional phase stability in medium-entropy and high-entropy Cantor-Wu alloys from an ab initio all-electron Landau-type theory and atomistic modeling Short-range order in high-entropy alloys (HEA) prompts exciting physical questions: What are the implications for material properties, and what underlying mechanisms are drivers? In this theoretical w...

Next, my first 'first-author' article, published as an #EditorsSuggestion in Physical Review B in 2022:

doi.org/10.1103/Phys...

We proposed a new technique for studying phase equilibria in #HighEntropyAlloys, combining #DFT calculations, a concentration wave analysis, and #MonteCarlo simulations
