The nucleation and growth of recrystallized grains or pearlite colonies can be viewed as a structural phase transition and modeled with a set of phase-field equations. Such a micromechanical formulation is consistent with the viewpoint taken in deriving the Johnson-Mehl-Avrami-Kologoromov (JMAK) equation and delivers essentially the same volume fraction kinetics. The differences can be explained in terms of the idealizations made in formulating the JMAK equation. The micromechanical model is… CONTINUE READING
