AVRAMI EQUATION INADEQUACY FOR MODELING THE HDPE ISOTHERMAL CRYSTALLIZATION RATES / Fallas de la ecuación de Avrami en el modelado de velocidades de cristalización isotérmica de Pead

open access: yes, 2013
The temperature dependence of the crystallization rate of polymers has been related to the classical nucleation and growthprocess. At temperatures slightly below the melting point, the controlling step is the nucleation process while, with ...

Kolmogorov-Johnson-Mehl-Avrami model fitted to early COVID-19 mainland China infection outbreak data [PDF]

open access: yes
In 2007 Avramov provided theoretical framework which suggests that the Kolmogorov-Johnson-Mehl-Avrami (KJMA) model, which is commonly used in materials science to describe transformation phenomena, could be used in describing infection spreading in human

Prediction of grain size in TB18 titanium alloy forgings by re-crystallization and grain growth modelling

open access: yesMaterials Research Express
After plastic deformation, metals and alloys will be in a thermodynamically unstable high free en-ergy state with a tendency to spontaneously return to a low free energy state. Understanding the laws of occurrence and development of these processes is of
