The mechanism of porosity formation during solvent-mediated phase transformations [PDF]

open access: yes, 2010
Solvent-mediated solid-solid phase transformations often result in the formation of a porous medium, which may be stable on long time scales or undergo ripening and consolidation.

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 ...

Thermodynamic Analysis of ArxXe1-x Solid Solutions Based on Kirkwood–Buff Theory

open access: yesPhyschem, 2022
Kirkwood–Buff Integral (KBI) theory is an important method for the analysis of the structural and thermodynamic properties of liquid solutions. For solids, the calculation of KBIs has become possible only recently through the finite-volume generalisation

Grain growth in ultrafine-grained Y-TZP ceramics [PDF]

open access: yes, 1997
Grain growth in dense ultrafine-grained (120–600 nm) tetragonal ZrO2-Y2O3 ceramics is studied as a function of temperature. At all temperatures investigated both segregation and phase partitioning occur.
