A micromechanical model for transformation plasticity in steels
TL;DR: In this paper, a semianalytical relation between the global deformations, the load stress state and transformation parameters can be given under the assumption of the same final strain tensor in each micro-region.

The use of the JMAYK kinetic equation for the analysis of solid-state reactions: critical considerations and recent interpretations
TL;DR: In this article, the classical Johnson-Mehl-Avrami-Yerofeev-Kolmogorov (JMAYK) equation is used for recrystallization of plastically deformed metals.

Hydration kinetics of composite binder containing slag at different temperatures
TL;DR: Based on hydration kinetics model, three hydration processes of composite binder, namely nucleation and crystal growth (NG), interactions at phase boundaries (I) and diffusion (D), were characterized, and the relationship between hydration rate and binder degree was discussed in individual periods.

TL;DR: In this paper, the influence of interrupted quenching (IQ) in the temperature range 150-250°C for periods of 15-1080s on artificial aging after long-term natural pre-aging was studied for the Al-Mg-Si alloy AA6061 by atom probe tomography, transmission electron microscopy, electrical resistivity and hardness measurements, and differential scanning calorimetry.

Dissipation-Theory Treatment of the Transition from Diffusion-Controlled to Diffusionless Solidification
TL;DR: In this article, the steady-state velocity of a planar liquid-solid interface is predicted by calculating the free energy dissipated by irreversible processes at the interface and equating it to the available driving free energy.
