Nanolamellar phase transition in an additively manufactured eutectic high-entropy alloy under high pressures

open access: yesAIP Advances, 2023
Much is unknown about how phase transitions link to micro-/nano-structures in high-entropy systems, especially under extreme pressure and temperature conditions.

Eutectic Reaction and Microstructure Stability in CoCrFeNiNbx High-Entropy Alloys

open access: yesMetals, 2022
Seven arc-melted and then annealed CoCrFeNiNbx (x = 0.3–0.6) alloys are experimentally and thermodynamically investigated in the present work. All the as-cast and 1000 °C annealed CoCrFeNiNbx alloys are composed of face-centered cubic (FCC) and C14 Laves

Formation of metastable bcc-δ phase and its transformation to fcc-γ in laser powder bed fusion of Fe–Mn–Si shape memory alloy

open access: yesJournal of Materials Research and Technology, 2021
The phase transformation behavior from metastable bcc-δ to fcc-γ in Fe–Mn–Si based shape memory alloy processed by laser powder bed fusion was investigated. Primary δ phase formed in this alloy due to the rapid cooling and fast solidification.

First-principles study of ternary fcc solution phases from special quasirandom structures [PDF]

open access: yes, 2007
In the present work, ternary Special Quasirandom Structures (SQSs) for a fcc solid solution phase are generated at different compositions, $x_A=x_B=x_C=\tfrac{1}{3}$ and $x_A=\tfrac{1}{2}$, $x_B=x_C=\tfrac{1}{4}$, whose correlation functions are ...

Two-phase coexistence in Fe–Ni alloys synthesized by ball milling [PDF]

open access: yes, 1996
We used mechanical alloying with a Spex 8000 mixer/mill to synthesize a series of Fe100–xNix alloys from x=0 to x=49. The Spex mill was modified so that it could also operate at a reduced milling intensity, and we compared the alloys synthesized after ...

The distorted-fcc phase of samarium

open access: yesJournal of Physics: Conference Series, 2014
Angle-dispersive x-ray powder diffraction experiments were performed on samarium metal up to 50 GPa. We report that the high-pressure distorted-fcc phase has the same hR24 structure observed in praseodymium, but, unlike praseodymium, samarium does not undergo a transition to a second distorted-fcc phase.

Phase evolution and solidification cracking sensibility in laser remelting treatment of the plasma-sprayed CrMnFeCoNi high entropy alloy coating

open access: yesMaterials & Design, 2019
The mechanism of solidification cracking in a laser-remelted bead of a plasma-sprayed CoCrFeMnNi high-entropy alloy coating was revealed. The oriented dendrite growth and phase distribution of the remelted bead were characterized by electron backscatter ...
