Effect of strain-induced precipitation on the recrystallization kinetics in a model alloy [PDF]

open access: yes, 2021
The effects of Nb addition on the recrystallization kinetics and the recrystallized grain size distribution after cold deformation were investigated by using Fe-30Ni and Fe-30Ni-0.044 wt pct Nb steel with comparable starting grain size distributions. The

Precipitation kinetics of Ti3Ni4 and multistage martensitic transformation in an aged Ni–rich Ni–Ti shape memory alloy

open access: yesJournal of Materials Research and Technology, 2020
The precipitation kinetics of Ti3Ni4 in a Ti–51.0 at.% Ni alloy was studied through the martensitic transformations temperatures and the JMAKE model. The influences of different aging temperatures and aging time on martensitic transformations temperatures

Modeling of Abnormal Grain Growth That Considers Anisotropic Grain Boundary Energies by Cellular Automaton Model

open access: yesMetals, 2022
A new cellular automaton (CA) model of abnormal grain growth (AGG) that considers anisotropic grain boundary energies was developed in this paper. The anisotropic grain boundary energy was expressed based on two types of grains, which correspond to two ...

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

open access: yesAdvanced Functional Materials, Volume 36, Issue 81, 8 October 2026.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Adsorbent Materials for Hydrocarbons Removal by Geopolymerization of Halloysite Clay Nanotubes Filled Within Chitosan Matrix

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 19, 6 October 2026.
Alkaline activation of halloysite clay nanotubes embedded in a chitosan matrix converts bionanocomposite films into porous geopolymeric materials with enhanced adsorption capacity toward hydrocarbons in both vapor and aqueous phases. The improved adsorption performance was demonstrated by the efficient capture of dodecane vapors and phenol from water ...

Extension of the Johnson-Mehl-Avrami-Kolmogorov theory incorporating anisotropic growth studied by Monte Carlo simulations [PDF]

open access: yes, 2006
An analytical theory has been developed, based on Monte Carlo (MC) simulations, describing the kinetics of isothermal phase transformations proceeding by nucleation and subsequent growth for d-1 dimensional growth in d dimensional space (with d 2 or 3 ...

Antisolvent crystallization of lithium hydroxide monohydrate: Significant factors and kinetics analysis

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 10, Page 5383-5396, October 2026.
Abstract Crystallization is the final stage in lithium hydroxide monohydrate (LiOH · H2O) production, and antisolvent crystallization offers a lower‐energy route compared with evaporative methods. In this study, we investigated bench‐scale ethanol‐based antisolvent crystallization of LiOH · H2O, and identified the significant impact parameter via a ...

Determination of the kinetic parameters for crystallization directly from isothermal DSC curves

open access: yesDiscover Chemistry
The determination of crystallization kinetic parameters is central to elucidating the transformation mechanisms in glassy systems, particularly when analyzed within the framework of the Kolmogorov–Johnson–Mehl–Avrami equation. In this paper, we show that
