ABSTRACT The development of ultrastrong maraging stainless steels (MSSs) is always in high demand. However, traditional high-strength MSSs generally exhibit early plastic instability with a low uniform strain since the precipitated nanoparticles are non-coherent with the body-centered-cubic (BCC) lath martensitic matrix. Here, we design a novel ultrahigh strength MSS (Fe-5.30Cr-13.47Ni-3.10Al-1.22Mo-0.50W-0.23Nb-0.03C-0.005B, wt. %) using a cluster formula approach. A fabulous microstructure con...

Abstract null null A local structure determines the properties in disordered solid solutions with simple crystal structure. Introducing a weak enthalpy-interaction-element will change the local structure evolution of refractory high-entropy alloy films, thereby bringing effects for the properties. Herein series of (NbMoTaW)100-xVx (x = 0 ∼ 30.5, at%) thin films were prepared by radio frequency magnetron sputtering, and systematic investigations of the films are carried out through combining the ...

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...

Titanium alloys are composed of α and β phases and are classified as near α, dual-phase α+β, and β types. This study attempts to derive their general composition formulas within the cluster-plus-glue-atom model by interpreting Ti-6Al-4V and other popular dual-phase α+β Ti alloys with well-established chemical compositions. Our model identified a molecule-like structural unit that covers only a nearest-neighbor cluster along with a few next-neighbor glue atoms, which can be represented as “[clust...

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...

Each conventional alloy has its own specific compositions but the compositional origin is largely unknown due to our insufficient understanding about chemical short-range ordering in the alloy, in particular, in the solid-solution state. In the present paper, the compositions of metallic alloys are discussed and formulated, by unveiling the basic moleculelike structural units in solid solutions. Friedel oscillation theory, which describes the partial charge screening behavior in solid solutions,...

Abstract Mg-Gd-Y-Zr alloys with high strength levels fall within narrow composition ranges. The present paper explains their composition rule by establishing the cluster-plus-glue-atom unit of Gd-containing Mg solid solution with the aid of Mg matrix and Mg5Gd precipitate phase. First, based on the structural homologue between Gd-containing Mg solid solution and Mg5Gd precipitate phase and in combination with our previously established method for calculating the glue atoms, [Gd-Mg12]Mg5 is obtai...

Abstract To balance the relationship between weldability and properties, a series of Ni-based superalloys with varying amount of Cr-like elements were designed using a “cluster-plus-glue-atom” model, and fabricated by laser additive manufacturing (LAM). The microstructure of the as-deposited superalloys consists of few topological close packet (TCP) phases distributed between γ-Ni dendrites with epitaxial growth characteristic. With the increase of Cr-like elements amount, TCP phases change from...

Abstract Three nickel-based amorphous filler materials with composition of [B-Ni9-xCrx]BSiNi (x = 0,1,2) were designed to braze K4169 superalloy according to cluster-plus-glue-atom model. The microstructure of K4169 nickel- based alloy brazed joints was examined, and the shear strength of the joint was also measured via pressure-shear tests. The brazed seam consists of γ-Ni solid solution, Nb6Ni16Si7 and CrB phases of joint brazed with [B-Ni7Cr2]BSiNi filler. More Nb6Ni16Si7 phase formed in the ...
