Atomistic Assessment of Solute-Solute Interactions during Grain Boundary Segregation [PDF]

open access: yesNanomaterials, 2021
Grain boundary solute segregation is becoming increasingly common as a means of stabilizing nanocrystalline alloys. Thermodynamic models for grain boundary segregation have recently revealed the need for spectral information, i.e., the full distribution ...

Unusual solute segregation phenomenon in coherent twin boundaries [PDF]

open access: yesNature Communications, 2021
Segregation of solute atoms at interfaces affects the properties of alloys and needs to be understood to allow their rational design. Here the authors report an unusual solute segregation phenomenon in a group of Mg alloys, driven by chemical bonding ...

Atomistic and machine learning studies of solute segregation in metastable grain boundaries [PDF]

open access: yesScientific Reports, 2022
The interaction of alloying elements with grain boundaries (GBs) influences many phenomena, such as microstructural evolution and transport. While GB solute segregation has been the subject of active research in recent years, most studies focus on ground-

Atomically ordered solute segregation behaviour in an oxide grain boundary [PDF]

open access: yesNature Communications, 2016
Solute segregation is challenging to experimentally identify at the atomic scale. Here, the authors report the direct observation of atomic site-dependent solute segregation behaviour in an yttria-stabilized zirconia grain boundary by atomic-resolution ...

First-principles study of the solute segregation in twin boundaries in Mg and possible descriptors for mechanical properties

open access: yesMaterials and Design, 2019
Twin boundaries play an important role in shaping the mechanical properties of Mg and Mg alloys. In this study, we simulate the segregation energies (SEs) of 23 solutes in the profuse {101¯2} and {101¯1} twin boundaries in Mg.

Simultaneously improving strength and ductility of Mg-Gd-Zr alloy via solute segregation

open access: yesJournal of Magnesium and Alloys
Interface segregation of solute atoms has a profound effect on properties of engineering alloys. In this study, we report a novel strategy for breaking the strength-ductility dilemma of Mg alloy via solute segregation. The hot extruded Mg-1.8Gd-0.3Zr (wt.

Solute redistribution and segregation in solidification processes [PDF]

open access: yesScience and Technology of Advanced Materials, 2001
In this review paper, research on solute redistribution coefficients for equilibrium, near equilibrium and non-equilibrium solidification processes were first analyzed. Then, different models advanced since the 1950s for solute redistribution during the directional solidification process with a planar interface were summarized.
