Refractory high-entropy alloys (RHEAs) with body-centered-cubic (BCC) structure are a new class of alloy materials and have great potential for high temperature applications. The present work investigated the BCC structural stabilities of Ti-Zr-Nb-Hf RHEAs with both first-principles calculations and experimental characterization. The cluster-plus-glue-atom model (cluster model) for the presentation of chemical short-range ordering (CSRO) in solid solutions was applied to construct the model inpu...

Abstract The present work proposed a characteristic-parameter-embedded machine learning (ML) model to predict and design body-centered-cubic (BCC) γ-U alloys with high corrosion-resistant lifetime in 343 °C boiling water in U-Mo-Nb-Ti-Zr systems. The characteristic parameters of cluster formula approach and Mo equivalence (Moeq) were implemented into the ML for a more accurate prediction, in which the former reflects the interactions among elements and determines their added amounts and the latt...

The present work investigated the formation and mechanical behavior of body-centered-cubic (BCC) Zr(Hf)-Nb-Ti medium entropy alloys (MEAs), in which three series of alloys, [Zr-Zr14](Zr,Nb)3, [Ti-Zr14](Ti,Nb)3, and [Ti-(Hf,Zr)14](Nb)3, were designed by the cluster formula approach. With increasing the Nb content, the BCC-β structural stability of the [Zr-Zr14](Zr,Nb)3 alloys would be enhanced, as evidenced by the BCC [Zr-Zr14](Nb)3 (Zr83.33Nb16.67 in atomic percent at. pct) alloy containing a mi...
