SUMMARY
The Johnson-Mehl-Avrami equation is a critical mathematical model used to describe the kinetics of phase transformations, particularly in recrystallization processes. This equation characterizes the time dependence of the fraction of transformed material and is essential for understanding crystallization dynamics. Key applications include materials science and metallurgy, where it helps predict the behavior of materials under varying thermal conditions. Resources such as Carnegie Mellon University's lecture notes provide comprehensive insights into its characteristics and applications.
