THE USE OF THE JMAYK KINETIC-EQUATION FOR THE ANALYSIS OF SOLID-STATEREACTIONS - CRITICAL CONSIDERATIONS AND RECENT INTERPRETATIONS

The present work is concerned with the classical Johnson-Mehl-Avrami-Y erofeev-Kolmogorov (JMAYK) equation. Some critical points are presente d because this kinetic relation has been extensively misused. Various aspects regarding its failure when it is applied to recrystallization of plastically deformed metals are also considered. Recent conceptual improvements, such as the new approach where the transformation is des cribed by the superposition of single JMAYK processes, have resulted i n the resurgence of this approach.
