Figure 9. A series of phase-field simulations were performed under systematic variation of cooling and nucleation conditions. Good agreement between (a) experimental microstructure and (b) simulated microstructure was obtained for an extraction rate of 2×1011 W/m3 and a nucleation density of 5×1016 m-3 .
