Crystallization of glasses - When to use the Johnson-Mehl-Avrami kinetics?

Roman Svoboda

Summary: The study tested the applicability of the JMA model based on the universal criterion of the kinetic peak asymmetry and determined the correlation between the simulated crystallization peaks and the JMA description. Results showed that the JMA model provided accurate kinetic predictions with high correlation coefficients within specific intervals of conversion degrees.

Analysis of non-isothermal polymer crystallization at constant scan rates based on the Avrami model

Akihiko Toda

Summary: In this study, a new method for examining the temperature dependence of crystal growth in polymer crystallization was proposed, utilizing the Avrami model. Parameters obtained from isothermal crystallization were used to evaluate crystal growth rate. The applicability of this method was confirmed through numerical calculations and experimental studies.
