A general model which combines growth of quenched-in nuclei and simultaneous nucleation with subsequent crystal growth was developed to describe the isothermal kinetic data. The rates of nucleation and linear growth as well as the activation energy for growth estimated on the basis of this model ...

The validity of JMA model to the kinetics analysis was checked. The changes in the microstructure and kinetic transformations have been linked to the evolution of the rolling temperature that introduced high density dislocations in initial phase and changes fraction and interaction between the β1 ' ...
The kinetic equation presented at the end of Oladoja's paper is worthless and may not be a feasible equation that can be applied to adsorption from solutions. 展开 关键词: Avrami fractional kinetic adsorption model Kinetics of adsorption Interpretation of Avrami equation ...
Crystal Growth Simulations To Establish Physically Relevant Kinetic Parameters from the Empirical Kolmogorov–Johnson–Mehl–Avrami Model A series of simulations was performed to enable interpretation of the material and physical significance of the parameters defined in the Kolmogorov, Johns...

Johnson-Mehl-Avrami kinetic equationMany solid state transformations follow the Johnson-Mehl-Avrami kinetic equation, particularly crystallization of polymers, glasses and amorphous metals. The value of the Avrami exponent in this relationship, important for understanding the reaction mechanism, is normally ...
