Polymer, 1997 The method reported in this paper is a simple means by which to determine the Avrami exponent, n, after cooling from the molten state of semi-crystalline polymers. This determination, often drudgery, has been significantly simplified, yet remains satisfactorily reliable.

Avrami exponent of crystallization in tellurite glasses
Journal of Thermal Analysis and Calorimetry, 2011 Nucleation process and crystal growth for three samples of the (20-x)Li2O–80TeO2–xWO3 glass system were studied using X-ray diffraction and differential scanning calorimetry techniques. X-ray diffraction data confirmed the amorphous characteristic of the as-quenched samples and indicated the growth of crystalline phases formed due to the thermal ...

Physical Chemistry Chemical Physics, 2011 The properties of ionic liquids give rise to applications in diverse technology areas including mechanical engineering, mining, aerospace and defence. The arbitrary physical property that defines an ionic liquid is a melting point below 100 °C, and as such, an understanding of crystallisation phenomena is extremely important.

On Discussion of the Applicability of Local Avrami Exponent: Errors and Solutions
Materials Letters, 2009Abstract The local Avrami exponent is usually used to evaluate nonlinear Kolmogorov–Johnson–Mehl–Avrami (KJMA) plots. But in some phase transformations, a changing kinetic exponent may result from the inappropriate use of kinetic model. A modified kinetic model considering the impingement effect has been introduced to show that when the KJMA equation

Accurate Determination of the Avrami Exponent in Phase Transformations
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 1991Abstract A method is proposed for the determination of the Avrami exponent in studies of phase transformations. In this method, the uncertainty associated with the estimation of the incubation time is greatly reduced. We have used this method in analysing the isothermal crystallization kinetics of a metallic glass Fe 75 V 1 B 24 . The results give an

Avrami Exponent of Crystallization in Metallic Glass Cu73.8P13.8Ni8.3Sn4.1
Journal of Materials Science, 1992A non-isothermal method has been developed to measure the Avrami exponent of crystallization in metallic glass based on the Johnson-Mehl-Avrami isothermal equation. An example of metallic glass Cu73.8P13.8Ni8.3Sn4.1 was studied with non-isothermal and isothermal kinetic analysis for determining the Avrami exponent,n, which are 3.5 and 3.4, respectively,

Avrami Exponents for Transformations Producing Anisotropic Particles
Journal of Non-Crystalline Solids, 1996Abstract The behavior of Avrami exponents (AE) for systems which produce anisotropic particles (for which shielding effects and phantoms occur) is examined. Probabilistic arguments used in previous studies are applied to derive expressions for the AE as a function of time or the extent of transformation. Numerical calculations for the one dimensional
