An FCC phase in a metastable β-titanium alloy

Philosophical 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.

First-principles calculation of phase transitions and mechanical properties of (CoCrNi)100−xAlx (0 ≤ x ≤ 28 at. %) high-entropy alloys

AIP Advances
In the two-phase high-entropy alloys (HEAs) (i.e., FCC, BCC), the modulation of the BCC phase is crucial for improving the mechanical properties of FCC-type HEAs. The stability of the phase of (CoCrNi)100−xAlx (0 ≤ x ≤ 28 at.

Estimation of the chemical compositions and corresponding microstructures of AgInCd absorber under irradiation condition

Nuclear Engineering and Technology, 2020
AgInCd alloy is widely used as neutron absorber in nuclear reactors. However, the AgInCd control rods may fail during service due to the irradiation swelling. In the present study, a calculational method is proposed to calculate the composition change of

Microstructural evolution and strengthening mechanisms in CrxMnFeNi high-entropy alloy

Journal 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 ...

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

Metals, 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 ...

Solution of the Controversy in the fcc-Based Phase Diagram [PDF]

Progress of Theoretical Physics Supplement, 1986
The paper reviews the controversy on the shape of the fcc-based phase diagram near the triple point among the disordered (A1), L1z and L1o phases. The discrepancy was originally between the cluster variation method (CVM) results and Monte Carlo (MC) simulation results, but the contro­ versy developed into how to interpret MC results. The paper examines

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

Physical 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 ...
