We investigate the kinetics of phase transition for chiral symmetry breaking after a collision with high-energy heavy ions. We use a Langevin description for domain growth kinetics in the chiral phase transition. The Langevin equation of motion for the order parameter field includes dissipation and the {\it inertial term} with a Gaussian random force. We study the far-from-equilibrium ordering dynamics subsequent to a quench from the massless quark phase to the massive quark phase and discuss the effect of dissipation on the dynamic magnification. After a discussion on the growth of the bubble, we introduce the assumption of scale and to show how a dynamic correlation length emerges. We find a simple length scale corresponding to the Allen-Chan (AC) growth law i.e., $L(t) \sim t^{1/2}$.
