Phase Stability and Inverse Hall-Petch Effect of Severely Deformed and Annealed CrMnFeCoNi High-Entropy Alloy [PDF]

open access: yesArchives of Metallurgy and Materials
The reverse phase transition from hexagonal close-packed (hcp) to face-centered cubic (fcc) was studied using diffraction of high-energy synchrotron radiation and hardness measurements on the CrMnFeCoNi high-entropy alloy deformed by high-pressure ...

An FCC phase in a metastable β-titanium alloy

open access: yesPhilosophical Magazine Letters, 2014
A new face-centred-cubic phase is reported here in a metastable β-titanium alloy with an equilibrium α–β structure, formed due to solution treatment and ageing. The face-centred-cubic phase is located inside the close-packed-hexagonal α-phase and has an orientation relationship with α-phase.

Microstructural evolution and strengthening mechanisms in CrxMnFeNi high-entropy alloy

open access: yesJournal of Materials Research and Technology, 2021
In the present work, we reported the microstructure and mechanical properties of CrxMnFeNi high-entropy alloy (HEA). The microstructures of the HEAs were characterized by scanning electron microscopy (SEM) with electron back-scattered diffraction (EBSD ...

Ab initiomelting curve of the fcc phase of aluminum [PDF]

open access: yesPhysical Review B, 2002
The melting curve of the face-centered cubic (fcc) phase of aluminum has been determined from 0 to $\ensuremath{\sim}150 \mathrm{GPa}$ using first-principles calculations of the free energies of both the solid and liquid. The calculations are based on density functional theory within the generalized gradient approximation using ultrasoft Vanderbilt ...

Gradient Distribution of Microstructures and Mechanical Properties in a FeCoCrNiMo High-Entropy Alloy during Spark Plasma Sintering

open access: yesMetals, 2019
A novel graded material of a high-entropy alloy (HEA) FeCoCrNiMo was fabricated by spark plasma sintering (SPS) processing. After SPS, the HEA specimens consisted of a single face-centred cubic (FCC) phase in the center, but dual FCC and a tetragonal ...

Dynamics of the fcc-to-bcc phase transition in single-crystalline PdCu alloy nanoparticles

open access: yes, 2023
Two most common crystal structures in metals and metal alloys are body-centered cubic (bcc) and face-centered cubic (fcc) structures. The phase transitions between these structures play an important role in the production of durable and functional metal ...
