Avrami Equation

The Avrami equation describes how a solid transforms from one phase into another at constant temperature, and is used specifically to describe the kinetics of crystallization, more generally to describe other phase changes in materials such as chemical reaction rates, and even, in some analyses, changes in ecological systems. It is also known as the Johnson-Mehl-Avrami-Kolmogorov, or JMAK, equation, after Johnson, Mehl, Avrami and Kolmogorov, who first derived it across a series of papers published in the Journal of Chemical Physics between 1939 and 1941, building on Kolmogorov's own 1937 statistical treatment of the crystallization of a solid.
