Fig. 4: 2-D cross-sections of 3-D simulation results.

2-D cross-section of a 3-D simulation result, with the cooling rate of 5 K s−1 at a 851.02 K, b 847.89 K, c 845.07 K, and d 845.01 K, with the cooling rate of 10 K s−1 at e 850.89 K, f 847.14 K, g 845.86 K, and h 845.01 K, with the cooling rate of 100 K s−1 at i 850.48 K, j 847.14 K, k 845.09 K, and l 845.01 K. (α-Al is in blue color, Si is in yellow color, and the remaining liquid is in green color).
