Load Partitioning and Strain Compatibility in a Non-Equiatomic Dual-Phase AlCoCrFeNi High-Entropy Alloy Processed by Forging

Metals
The tensile and compressive behavior of hot-forged Al5Co35Cr30Fe20Ni5 high-entropy alloy (HEA) has been studied at room temperature. The forged HEA has a dual-phase microstructure consisting of a predominant face-centered cubic (FCC) matrix and a body ...

The BCC-FCC Phase Transformation Pathways and Crystal Orientation Relationships in Dual Phase Materials From Al-(Co)-Cr-Fe-Ni Alloys

Frontiers in Materials, 2020
The alloy system Al-(Co)-Cr-Fe-Ni contains compositional ranges where a solid state BCC-FCC phase transformation leads to dual-phase materials composed of face-centered cubic (FCC) and body-centered cubic (BCC) phases with nearly equal volume fraction ...

Large difference in the elastic properties of fcc and hcp hard-sphere crystals [PDF]

, 2003
We report a numerical calculation of the elastic constants of the fcc and hcp crystal phases of monodisperse hard-sphere colloids. Surprisingly, some of these elastic constants are very different (up to 20%), even though the free energy, pressure and ...

Unusual two-step dealloying mechanism of nanoporous TiVNbMoTa high-entropy alloy during liquid metal dealloying

Journal of Materials Research and Technology, 2021
In this study, 3D interconnected nanoporous (3DNP) TiVNbMoTa HEAs were synthesized from the (TiVNbMoTa)25Ni75 as-cast precursor alloy using the liquid metal dealloying (LMD).

Supersolid of Hardcore Bosons on the Face Centered Cubic Lattice

, 2007
We investigate a supersolid state in hardcore boson models on the face-centered-cubic (FCC) lattice. The supersolid state is characterized by a coexistence of crystalline order and superfluidity.

Ternary coherent phase diagram on the FCC lattice [PDF]

Journal de Physique I, 1994
In this paper, we describe a general and original method to study the ground state problem, in multicomponent systems. The method is illustrated by considering the nearest neighbour Ising model in ternary FCC lattices, and leads to the occurrence as a ground state of a new phase called L'.

Machine learning guided BCC or FCC phase prediction in high entropy alloys

Journal of Materials Research and Technology
High entropy alloys （HEAs） have excellent properties because they can form simple solid solution (SS) phases, including body-centered cubic (BCC) phase, face-centered cubic (FCC) phase, or FCC + BCC phase, so phase prediction is the first step in alloy ...

Crystalline and Electronic Structures of Molecular Solid C$_{50}$Cl$% _{10}$: First-Principles Calculation

, 2006
A molecular solid C$_{50}$Cl$_{10}$ with possible crystalline structures, including the hexagonal-close-packed (hcp) phase, the face-centered cubic (fcc) phase, and a hexagonal monolayer, is predicted in terms of first-principles calculation within the ...

Synthesis and Self-Assembly of fcc Phase FePt Nanorods

Journal of the American Chemical Society, 2007
We report a synthesis of FePt nanorods by confining decomposition of Fe(CO)5 and reduction of Pt(caca)2 in surfactant reverse cylindrical micelles. The controlled nucleation and growth kinetics in confined environment allows easy control over Fe/Pt composition, nanorod uniformity, and nanorod aspect ratio.

Nanoindentation into a dual-phase bicontinuous lamellar high-entropy alloy

Journal of Materials Research and Technology
The plastic response of a dual-phase high-entropy alloy to nanoindentation is studied using molecular dynamics simulation. The sample has a bicontinuous lamellar structure consisting of an equiatomic FeNiCrCo fcc phase and an Al50(FeNiCrCo)50 bcc/B2 ...
