Definition

A phenomenological kinetic relation for isothermal phase transformations giving the transformed fraction X(t) = 1 − exp(−K t^n), where K is a rate constant and n (the Avrami exponent) reflects nucleation behavior and growth geometry under model assumptions (isothermal conditions, homogeneous nucleation or site saturation, isotropic growth, and simple impingement treatment).
