On the kinetics of phase transformation of small particles in Kolmogorov's model [PDF]

open access: yesCondensed Matter Physics, 2008
The classical Kolmogorov-Johnson-Mehl-Avrami (KJMA) theory is generalized to the case of a finite-size system. The problem of calculating the new-phase volume fraction in a spherical domain is solved within the framework of geometrical-probabilistic ...

Electrical Resistivity Change Upon Crystallization as a Robust Descriptor for Metallic Glass Forming Ability. [PDF]

open access: yesAdv Mater
Electrical resistivity change upon annealing is introduced as a rapid descriptor for identifying high glass‐forming ability in metallic glasses. High‐throughput combinatorial thin‐film libraries reveal that compositions exhibiting small resistivity changes correspond to sluggish crystallization behavior and known bulk metallic glass regions, enabling ...

Strain Tuning the Kinetics of Topotactic Phase Transitions in Epitaxial Oxide Films. [PDF]

open access: yesSmall Sci
We investigate the topotactic phase transition in epitaxial strontium cobaltite (SrCoOx) thin films. Our findings reveal asymmetric switching kinetics between the oxygen‐deficient SrCoO2.5 and oxygen‐rich SrCoO3 phases, driven by the epitaxial strain state.

Kinetics of conversion of brushite coatings to hydroxyapatite in alkaline solution

open access: yesJournal of Materials Research and Technology, 2018
This work describes the kinetics of conversion of brushite coatings, produced by chemical deposition, to hydroxyapatite. The conversion was performed in alkaline solution at three temperatures: 50 °C, 55 °C, and 60 °C. The evolution of the transformation
