A description of the competitive growth is presented in the paper. The description is associated with the competition between eutectic structure and primary phase formation. A coupled zone for the eutectic solidification is drawn in the phase diagrams. The coupled zone is shown as a range of solute concentration versus under-cooling to justify the formation of the eutectic structure, exclusively. Interface growth temperatures of the single and coupled eutectic are illustrated schematically as a function of growth rates at a given composition Co.
